The assassination of President John F. Kennedy is the greatest murder mystery in American history.
That's Rob Breiner. Rob called me, so would Edo Brein, and asked me what I knew about this crime.
We'll ask who had the motive to assassinate a sitting president.
Then we'll pull the curtain back on the cover-up. The American people need to know the truth. Listen to Who Killed JFK on the iHeartRadio app, Apple Podcasts, or wherever you get your
podcasts.
There's so much news happening around the world that we're somehow supposed to stay
on top of.
That's why we launched The Big Take.
It's a daily podcast from Bloomberg and iHeartRadio that turns down the volume a bit
to give you some
space to think.
I'm Wes Kosova.
Each weekday I dig into one important story and talk about why it matters.
Listen to the big take on the I Heart Radio app, Apple Podcasts or wherever you listen.
Q Josh Trumpet
You know what that means everybody.
We are going back on tour again.
We are hitting the road next year in January for our annual Pacific Northwest and Northern
California swing.
And we will be at the Paramount Theater in Seattle on January 24th, Revolution Hall
in Portland on the 25th, and our home away from home at San Francisco
Sketchfest on January 26th.
Yeah, we'll be at the Sydney Goldstein Theatre again, everybody.
Great place.
That's right.
If you want tickets and information, you can go to link tree slash S.Y.S.K. and it's
got all that jam.
You can go to our website stuffyshodone.com.
It's got all that jam and we will see all of you guys in January
with bells on. Welcome to Stuff You Should Know, a production of I Heart Radio.
Hey and welcome to the podcast. I'm Josh and there's Chuck and Jerry's here too and this is the
podcast I'm Josh and there's Chuck and Jerry's here too and this is the we'll get through it edition of stuff you should know about the periodic table. I have other names for it. I bet you do.
Can you say any of them? This is the only time I hate my job edition. This is the,
Well, this is the, now we can stop talking about the sun episode. Maybe.
Edition.
Uh-huh.
Uh, and this is the, my God, why do we ever do episodes on chemistry edition?
I failed chemistry.
It's the only thing I've ever failed was chemistry.
I don't think I even ever took chemistry to tell you the truth.
He didn't fail it.
Right.
He didn't fail if you don't try.
Yeah.
That's my motto.
Here's what I figured out about this.
Like driving myself mad,
trying to learn this stuff and understand it.
There is a lot of people out there
who have written articles and explainers
on the stuff that we're going to talk about who literally
don't know what they're talking about and yet they're presenting their information like they do
and it's wrong and it's you can't understand it or in cases where you can't understand it,
it still doesn't fully answer the question. There's a lot of stuff out there like that on this,
especially as it gets more and more like arcane, right?
Yeah.
There's a whole group of people out there,
chemists, molecular chemists, physicists,
who understand this, but you can put them all together
and they can't coherently explain any of it
to anybody else.
They can just talk to one another like this.
Where we are, where us and everybody listen
in this episode right now is stuck in the middle. We know enough that we can, we can notice when somebody is wrong,
or not correct, or doesn't know what they're talking about, but we don't know enough to
understand what the actual scientists are saying, and then come back and explain it. So, first
of all, Breton cap off to Livya for helping us with this one.
Boy, Livya should get a bonus for this one, quite frankly.
For sure.
And then second, we might have to edit that out.
Right.
Secondly, we're smarter enough to get all this across.
We are.
But we're also transparent enough to admit when we're like,
we don't understand this part.
Yeah, I mean, there's a few parts I still don't get.
I imagine the good news is I imagine that maybe
about 20% of our listenership
is even hearing this right now.
I hope more than that,
because it's really interesting stuff.
Would you click on something called
how the periodic table works?
Well, we're going to have to come up with something else.
I think we'll call this one legs, legs, legs.
Hahaha.
Colin, tiny lettering periodic table.
Exactly.
Hahaha.
The sex episode.
Right.
We'll see.
We'll trick them into listening to it.
All right.
I know I can get some of this at the beginning. So if you allow me to talk
about one of the only parts I understand.
Sure.
All right. Great. I'll kick it off.
Because we have to set the stage sort of for pre-periodic table construction, which
is to say that early, I'm sorry, late in the 18th century, we were working from sciences working from the Aristotelian,
Aristotelian, yeah, that's to say Aristotle system, which we've talked about some recently,
which is hey, we got four elements, fire, earth, water, and air.
And then after that, science became a little more nuanced and they're like, hey, actually, we think there are more things out there, more building blocks. And maybe we can
distinguish them from one another and categorize them, maybe based on their mass. And this was sort
of the scene when in 1804, an oddly, an English school teacher who is also a researcher named john dotton uh... said
alright um...
things are made up of smaller things
maybe these which is not new like for
you know ancient cultures were even talking about things being up of smaller
things
yet we talked about democratic in that episode about yet we believe before the
scientific method
totally that's exactly where it was
uh... he said things are made up maybe of like these little
tiny indestructible, indivisible atoms.
He got a lot of that wrong, but one thing he got right
was the idea that no two elements that we know about so far,
which were not very many at all, at that point,
can have an identical mass and all the atoms
of that element have the same mass,
which also wasn't quite right,
but at the time, it was right.
Yeah, because you got to give it up to these guys.
When we're like analyzing elements and atoms and stuff today,
we're using like spectrometry
and particle accelerators and doing all sorts of amazing stuff,
these guys are like burning things.
This is 1804.
Boiling them in acid, yeah.
Like they were doing all the stuff that a high school
chemistry teacher does to demonstrate chemistry.
That's what they were doing to actually isolate elements
and like weigh them.
They were weighing things like oxygen.
Like they figured out that if you take a liter of oxygen,
you will find that it weighs 1.5 grams.
No matter where in the world you weigh it,
it's going to weigh 1.5 grams.
Like that's what these people are doing.
Can you capture a leader of oxygen?
I can't.
I can't.
So I mean, what they were doing was the hard core,
like bloody, like roll up your sleeves kind of chemistry.
Like apparently it was like one of the biggest scientific pushes of the 19th century
was identifying elements.
And John Dalton was the first to say, hey, some of these, I think we can kind of like try
to organize them a little bit.
And Dalton didn't discover any elements from what I understand.
He was just the first one to come up with atomic theory in the modern age and try to start
ordering them based on atomic weight.
Yeah, exactly.
It wasn't quite the periodic table yet, but it was a precursor for sure.
And his very first version in 1803 only had the five elements that we knew about at the
time, hydrogen, oxygen, nitrogen,
carbon and sulfur.
Nitrogen was known as, and I think we said this in the other episode, the azote.
It was the azote?
I guess.
I guess.
Okay.
AZO-TE.
His second list, just five years later, was up to 20 elements, and then 24 years later,
by 1827, that list was up to thirty
six
uh... and as science was progressing
they started noticing patterns
and they started noticing sort of
uh... intervals where
things would repeat themselves such
that all of a sudden that german chemist named you on wolfgang and eighteen twenty
nine said
well wait a minute we're noticing these patterns.
And some of these things are the same. Like, if you look at lithium, sodium, potassium,
they have very similar properties. And we might can group those together. And those three
in the modern periodic table are grouped together in the same column. So he was, he was
right on the money as far as that idea.
Yeah. And I mean, we as humans are obsessed with finding patterns and things, and like discovering
a latent pattern in nature. I mean, there's a few things more exciting than that. So these guys
were looking for patterns even in places where they didn't necessarily exist, maybe maneuvering
things where they should or shouldn't be. Some people took some cracks at it to try to,
to try to kind of organize these elements by pattern,
but they ran into some problems.
One was the chemistry wasn't as exact
as it needed to be to really organize stuff.
There were elements that hadn't been discovered yet,
so there were big missing chunks,
but they didn't necessarily know there are big missing chunks,
but they were on the right track that you could order these things one way or another. And when
you did, they would start showing patterns, periodicity. Periodic table means that there
are periods or patterns that repeat themselves, depending on how you organize these elements. Yeah, and the the modern periodic table that we know and
loath
Sorry, I
Loath that thing that they pull down in science class that you know
Teenagers just blankly stare at not knowing what the heck they're looking at, but it's pretty sure if you say so
at, but it's pretty. Sure. If you say so. We owe that to a Russian chemist named Dimitri Mendelov. And Mendelov in 1869 was working on the very
first Russian language, organic chemistry textbook in 1869 and said, you
know what, we have 63 elements at this point. I think we can organize these.
And he did so.
He arranged things in columns.
He had to reorder some things from the previous order.
So he's like, maybe we shouldn't organize just by atomic mass.
Maybe we should order them into these similarities and how they behave.
And the big, big thing that Mindalov landed on was
leaving gaps where he saw gaps.
And instead of just, you know, buttoning it up
and making it look a certain way,
he said, I'm gonna leave a gap here.
And this is actually what kind of proved his worth
in the fact that he was really on the right track
because in the 15 years following him leaving those gaps, three
elements were discovered that fit those very gaps that he had left, perfectly, like a
little puzzle piece.
It's like the molecular chemistry version of Babe Ruth calling a shot.
Yeah, basically.
Essentially.
So, like when it turned out in the next 15 years, they found those elements that did not
only fill those spots, but they had properties that
Mendel have predicted they would.
Like they were like, you did really good guy.
He also predicted some other ones that didn't come true, but everybody was just like, whatever
it's fine.
So that was like the model that everybody used from that point on.
And it's the classic model that we see today where it's kind of like a castle
with turrets on either side and you know the brick in the middle and then there's like a couple
of rows below that are a moat if you squint hard enough. That's Mendelift who came up with that
whole thing. And the way that there are arranged is not by atomic mass but by atomic number.
That's why if you look and we should probably say the way you read the periodic
table is from left to right and top to bottom, right? So the whole thing starts in the top left
with number one hydrogen. And the reason it's number one is because it has one proton.
It's the best. That's right. It has one proton chuck and because it has one proton and its
stable form it has one electron. And all that's going to be important in a minute.
That's right.
I mean, should we go ahead and take a break?
I feel like that was kind of good setup, material.
Sure.
All right, we'll take a break and we'll be right back with more things to enlighten you
in NumU. The assassination of President John F. Kennedy is the greatest murder mystery in American
history.
That's Rob Breiner, Rob called me, so would Ed O'Brien and asked me what I knew about
this crime.
I know 60 years later, new leads are still emerging.
To me, an award-winning journalist, that's the making of an incredible story.
And on this podcast, you're going to hear it told by one of America's greatest storytellers.
Well, ask who had the motive to assassinate a sitting president?
My dad, 5JFK, screwed us at the Bay of Pigs,
and then he screwed us after the Cuban Missile Crisis.
We'll reveal why Lee Harvey Oswald
isn't who they said he was.
I was under the impression that Lee was
being trained for a specific operation,
then we'll pull the curtain back on the cover-up.
The American people need to know the truth.

You take my breath away.
I spent the last 15 years in my life fighting like hell to make sure that I never ended up here.
But then, I met her.
The name's Anna.
Hey, Anna, I'm Nico.
Didn't realize you were a professional musician.
From interval presents, a new romantic thriller podcast,
starring Jason DeRulo and Alexandra Ship.
There's someone about you that I haven't been able to look away from.
You go, we don't even know each other.
Let's no turn it back if we do this.
I've already made my decision.
This is what happens when you don't follow orders.
Nicholas.
No!
Nicholas! No!
I'm the water!
Listen to underwater on the I Heart Radio app, Apple Podcasts, or wherever you get your
podcasts. All right, so the modern periodic table, I think where was Mendolev?
He had 63 on his first.
Yeah, 63 known elements at the time on his first stab.
The modern periodic table right now stands at 118 and I think they've already
said they think possibly maybe one day it may top out at 173. We'll see. We'll see, but
that's sort of, you know, the thinking, the logic. But right now we're at 118 elements
that we know about. It includes on the chart the name of the element. They're usually
a one or two letter symbol, which is almost always short for the name, but in a case of
gold, like when you see AU for gold, and you're like, what the heck is that all about?
That just means it's based on the original Latin for gold, RM. And they are placed like you said before the break in order of their
atomic number, which represents the protons in each atom. And that is what makes that each
element unique over those seven rows, a.k.a. periods, and 18 numbered columns, a.k.a. groups.
Yeah. So the rows across across horizontally those are the periods.
And like you said, it's really important to remember, if you take a proton and add it
to an element, you don't have like a variation on the element.
You have an entirely new element.
Everything else you can mess around with fudge, mess with the neutrons, mess with the electrons.
If you add a proton or take away a proton, you got a totally different element, which
is why you can order them by their atomic number, number one with hydrogen, number two helium,
which has two protons and so on and so forth. When you see that little number in the top left of
the square for that element, that's how many protons it has. But again, as we'll see, if we're talking about on the periodic table, stable atoms, that
means that they don't have an electric charge, they're neutral, and that means that they
have an even number of protons and electrons.
Protons are positively charged, electrons are negatively charged, and if you have one
and one, they cancel each other out.
Two and two, they cancel each other out, or at the very least, they make the electric charge neutral.
All right.
So if you're looking, if you brought up a picture by now
of the periodic table,
because you really want to follow along,
first of all, God bless you for doing such a thing.
And secondly, you might say, oh wait a minute Chuck,
what's that thing underneath everything? We'll, well, wait a minute, Chuck, what's that thing underneath everything?
We'll get to this in a minute, but those 14 short columns underneath is called the F block.
And those are the 7th and 8th periods, aka rows, that are detached, and those are unnumbered
rows, whereas the other rows are numbered through 18.
So put a pin in the F block.
All elements within a period,
and again, that is the row, if you're looking for a zonal,
all the elements on each row
have the same number of electron shells.
And when you think about that in your mind's eye,
you're probably picturing how we think of that
in our mind's eye because of chemistry class and science class,
which is a circle around an atom's nucleus
that holds electrons.
Right.
Like an orbit.
That's Niels Bohr's contribution, although he made plenty of contributions, but the whole
idea that we have of that atom being consisting of a nucleus that's kind of like the sun,
an electrons orbiting around it like planets.
That's thanks to Neal's Bohr.
And the actual orbit, let's say you have just one circle around the nucleus.
That's a shell. It's one shell. And another one, that's the second shell.
And another one, that's the third shell. And they actually fill up in order.
So when you follow along across the rows, the horizontal rows, called periods
on the periodic table, all of those in that row have the same number of shells. One shell,
and the second shell, and the third shell, and the fourth shell. And as you go down, each
row has the, all the shells that the ones above it had, and now they've added another shell
because their other shells are full of electrons. Right. So if you look at periodic table, But all the shells that the ones above it had, and now they've added another shell because
their other shells are full of electrons.
Right.
So if you look at periodic table, get out your little picture, and you look at that first
row or period, that means it just has one shell capable of holding up to two electrons.
And so that's why there are only two elements there.
Hydrogen usually has one electron
and helium, which normally has two. And then you go down from there, the second and third
gels can hold up to eight electrons. So those second and third rows are each going to have eight
elements and so on. For the fourth and fifth, it's 18, the sixth and seventh, hold 32, and so there are 32 elements on the 6 and 7th rows.
Um, just to demonstrate a little further, so helium has two electrons in that one shell,
helium's full.
The first element on the next row that has a second shell, that's lithium.
Lithium has two electrons in its first shell, that's full, but it has an extra electron,
so now it's added another shell, the second shell, to house that first electron, and you go
all the way down to the very end of that row, that lithium starts, and you find neon, neon
has ten. Its first shell of two is full of electrons, its second shell they can hold
up to eight is full, so it has ten total electrons. This is what the periods are showing us.
The number of shells, and then eventually in a second,
we'll know the number of electrons that can fill those shells.
That's right, and the periods of the rows.
We're going to say that a thousand times,
groups or columns, periods or rows,
because if there's one takeaway from this whole thing,
you can at least look smart,
and when you walk into a room with a periodic table chart and say
and someone says, what are those rows and columns? And you can say, do you mean groups and periods?
Yeah, and then really quickly after that, look at your watch and be like, look at the time I'm late!
Right, and run out of the room so that there's no follow-up questions.
Yeah, and make a U-shaped hole in the wall. Not the letter U, but a Y-O U-shaped.
Yeah, nice. Did that come through? Sure.
It did once you spelled it.
The groups are what we're going to talk about next,
and those are the columns.
And this is where Mindalove realized these patterns
were coming into play.
And once subatomic theory came about,
and we started being able to drill down further and further,
we started to be able to get way more specific.
So, these patterns in these rhythms on the columns are based on the number of valence
electrons for each element, which means how many electrons you would normally find in
that outer most shell.
Yeah, the outer most shell is important, Chuck, because that's where all the action happens.
That's when atoms bond together to make new molecules.
That's where the attraction or repulsion happens.
Like that is the, that's the, the active shell.
All the other shells are full.
And when a shell is full, it's basically content.
It just wants to sit there.
It wants to be left alone.
But if that outermost shell isn't full,
then it's ready for
some action. It's got its leather jacket on, it's got its dissonance pocket, maybe a switch
blade, and it's looking for trouble. So more than I think even rows, like all of the elements
that are in a row, remember horizontal across a period, they're related because they all
have the same shell, the same number of shells, one, two, three, four, and so on.
The groups up and down, the columns,
they're more related, really,
because they have the same number of electrons
in that outer most shell.
They can have a bunch of different numbers of shells,
like for example, I think flooring can have five shells
but only one electron in that outer most shell.
Or it could have one shell and just have one electron in that outer most shell like a hydrogen.
They're more related because they'll react to other things more than they would if they
had different numbers of electrons.
Yeah.
We can add something to something you should remember,
because this will make you look even one step smarter
before you run out of the room through the wall.
Just say, oh yeah, it's organized into periods and groups,
and the periods of the rows and the groups of the columns
in, if you ask me, the columns, aka groups,
that's really where it's at.
They're more related.
They're more related. And then you run
through the wall. Right, so let me give you an example here, okay? All right, this is if you want
to really, really, really be smart, you remember this. Right. If you have your periodic table out,
really honestly, it will make this whole thing so much easier. But if you look all the way down to
the second group from the right that starts with fluorine.
If you look at fluorine, it has I think nine electrons, and it's in period two, so we know
that it has two shells.
So we know that it has two electrons in its first shell, so it must have seven electrons
in its extra shell, or its second shell.
And since we know that the second shell can hold 8, there's one little irritating gap
and it wants to fill it.
So fluorine is super duper reactive.
On the other hand, you've got things like potassium.
It has only one electron inside our most shell.
And it wants to actually get rid of that electron.
Because I think I said earlier earlier when a shell is full,
the atom is content and happy.
It doesn't want to do anything with anybody.
If it just has one left over, like one hole or one electron, it either wants to get rid
of that one electron so that it can lose that shell and go down to the next shell, which
is full, or it can fill it shell like fluorine wants to with the next year electron.
Either way, they're super reactive.
And it all happens in that outermost shell, the valent shell, and that's where all the
action happens.
Yeah.
And you know what, something we haven't even said that I think is important that dawned
on me.
What?
Is the periodic table, isn't just a, like, let's just do this thing so we can group them together.
A periodic table, the periodic table is made and it's organized this way.
So chemist and people that really know what they're doing can look at a poster on a wall
at any of those squares and know because of where it is on the row, where it is on the
column, what color it is and what block it is, and we'll get to those things
in a minute, and they can know a lot of very specific things
just because of where it sits and what it looks like
and what color it is.
Yeah, they can tell you whether it's gonna blow up in water.
Like, I guess apparently sodium, pure sodium does.
They can tell you if it's shiny.
All of this has to do almost entirely with the number of electrons it has
in its outer most shell.
All that stuff.
And that's the evolution of the periodic table.
People notice properties, physical properties,
they notice appearance, stuff like that.
And then as they learned more and more about the atom,
they figured out why in the atom,
those properties existed.
And they were able to classify those things together
in the periodic table.
So like you said, a chemist today can look at that
and be like, oh, that's going to be a shiny metal
that'll explode in your hand if you look at it wrong
because it's in this group of elements, right?
And I saw it described by a chemist really well.
If you, like,
to a chemist, a periodic table looks like a map to us. Like, if you look at a map of
the United States, you know that if you are looking at some place in the north, it's
going to be colder there than say somewhere in the south. You don't know exactly what the
temperature is or anything like that necessarily, but you know generally based on this map.
It's a map to the elements.
Yeah, and it also might, you know, you might think if you're looking at a map of the South, like that's where people are more like this.
And in the Midwest, people maybe, you know, a map tells you a lot more than just like what the weather's like.
Yeah.
Just like a periodic table.
So if a scientist, if a chemist looks at silicon,
I look at it and I see a capital S lower case I,
the word silicon, the number 14 in the left hand corner
and that it's yellow.
A chemist looks at it and says,
well, I see it's in between on the row,
aluminum and phosphorus and in the column, it's below carbon and above
germanium, and I see its number is 14, and it's yellow, which means it's a medalloid,
so I can tell you, like, these 12 things about silicon, just because of where it sits on
that map.
Yes.
It's pretty amazing.
I don't get it, but it's amazing.
Right.
I was just going to say, we're not going to explain what those 14 things are
because no, the kind of things you have to go to graduate school and chemistry to truly
understand. It's okay that we don't understand it. All you have to take away from this and
all we're trying to get across is that trained chemists can look at the periodic table and
realize a lot about whatever element they're looking at and figure out how to mix it with other elements to do amazing things
or if you put together these two things, this is probably the reaction that you're going to have.
Yeah, and it's also for someone like us that can get really confusing
because when you look at different periodic tables, one thing you'll notice
is that the colors may be different.
Like, there
is no, unless I'm wrong, there isn't one completely settled. This is the only way to do it periodic
table.
No.
As far as a lot of it goes, but depending on who you are and how you want to organize a periodic
table that you use, those colors may mean different things, so it can get really, really
confusing when it comes to that stuff. those colors may mean different things, so it can get really, really confusing
when it comes to that stuff.
For sure.
And usually there is like a key or a legend
on the periodic table that says,
this is what these colors mean.
But if you take away the colors,
the layout of them across and down,
if you look at a periodic table,
that's generally going to be the same
for any periodic table that looks even roughly like what you're looking at. It's the colors that really kind of change
things up. But more and more, as we've learned more about the atom, starting in the early
20th century, onward, and quantum mechanics kind of became a thing, that got incorporated
into the periodic table as well. And that is where we get to essentially the third way that the whole
thing is organized, which is by blocks, sub-shells, SPD and F. And so, take it away. The number of shells
an element has, that's its period across.
The number of electrons in its outermost shell,
that's its group, the blocks describe
where that outermost electron is.
And if you allow me for a second
to just kind of take a little divergence here,
it helps you understand it, I think.
Please, can we talk about baseball?
No, not that kind of divergence, like deeper into chemistry kind of divergence.
Okay, I'm going to go out and think about baseball.
Okay, so that whole model that Nils Bohr gave us of like the planetoid nucleus and the sun-like
nucleus and the planetoid electron orbiting it,
that is really off.
That's not at all what they're like.
It's good for people who don't really care
about this kind of thing to walk around thinking,
but when you actually start to try
to understand the periodic table,
it really gets in the way.
So if you can kind of throw that out,
and instead think of electrons as not particles like planet
hoids, they're actually waves of energy, right?
And they like to orbit atoms because their negative electrical charge is attracted to the
positive electrical charge of the protons.
That's why they're orbiting or flying around that nucleus.
But they don't do it in like these tight little orbits, like a planet does around like
the sun.
Instead, they inhabit three-dimensional areas that follow predictable shapes depending on
the energy level of that electron.
You can say what shape it's going to follow around that nucleus. but you can't say where it is at any given point in time
Thanks to our friend Heisenberg's uncertainty principle Heisenberg said you can know the velocity of
An object or you can know the location of a quantum object. You can't know both and because we know the
Energy of an object we can figure out
its velocity, its speed, like an electron, which means we can't know where it is. So these
orbits actually are where they may be 90% of the time. That's what an actual electron orbit
is. And again, it follows this weird, cool looking little three-dimensional, four-leaf,
clover shapes just really neat. And depending on the energy of the electron, it's going to
inhabit a specific place, 90% of the time, around the nucleus of that atom, either close to
the atom, further out, further out, depending on the shell that it's associated with. And the block is where the highest energy, the outermost electron, is in that position.
And again, it's denoted by SPDNF.
And it gets way more arcane than that.
But all you have to remember is that when you're looking at blocks, they're talking about
the specific location of the most energetic electron.
And again, since the outermost electrons are where all the action happens, the most
energetic of the outermost electrons are really where the action happens.
And that's why it's become a little more sophisticated, a little more refined over time,
thanks to the addition of quantum mechanics
in our understanding of the atom.
Are you there Chuck?
Did you go outside?
Sorry, I just came back in.
I didn't actually think about baseball,
which is kidding, I watched an entire baseball game.
Oh, who won?
I have no joke.
My brain is too mushy for a joke right now.
No, I actually listened to that
and I learned from you, so I appreciate that.
Thank you, because I felt like I was hanging from a trap piece
by my fingernails.
Well, I was underneath you with a net.
That's all I'm good for.
Thanks, buddy, I appreciate it.
And by the way, I didn't want to just walk past
that's all you're good for.
I just couldn't even bring myself to recognize
such a dumb thing that was said.
I appreciate that.
So the final thing we got to talk about
is kind of brings it back to the beginning
of how they originally just started to think about
grouping things, which was by their atomic mass,
that the sort of very basic thing that they first thought
they could use as a grouping device.
And they still will indicate the atomic mass on most periodic tables, but the atomic mass
is actually a weighted average of the amount of protons plus neutrons, but it depends
on how abundant different isotopes in that element are out in nature.
And it's not always the same.
So, carbon is a great example that Livia used. It always
has six protons. Usually has six neutrons, but sometimes can have seven or eight. So instead
of having an atomic mass of just 12, six plus six, they take a weighted average and it
weighs out to 12.011. So, if you see those numbers with a decimal point, you can understand
that that's because it's a weighted average
and not just a locked-in number.
Yeah, and just it doesn't necessarily have much to do
with the periodic table, but you've mentioned isotopes,
and all those are as an element with more or less electrons
than it has when it's stable in a neutral charge.
If you take away an electron, it has more positively charged
protons than electrons.
So that's a positive ion.
If you add an electron, like, say, fluorine wants to do, it becomes a, it has more electrons
than protons, so it becomes a negatively charged isotope.
So those are possible, too, but just bear in mind, you're not changing the number of protons,
because if you do that, you have a new element, you're just changing the number of electrons.
Either adding or taking away.
And one of the other things about the periodic table is you can point to different sections
and be like, those are the ones that form positive ions because they give away their
extra electron.
Those are the ones that form negative ions because they attract extra electrons, so they normally
have in their neutrally charged state.
That's another thing that you can just point to
at the periodic table.
Pretty amazing.
It is.
I mean, the fact that people have figured this out
is just hats off to all of the scientists
that were involved in this over the years.
Yeah.
I say we take a break.
Sure.
And when we come back,
we're gonna tell you about how things got very interesting
in terms of the periodic table in the 1930s, right after this.
The assassination of President John F. Kennedy is the greatest murder mystery in American history.
That's Rob Breiner, Rob called me, so let Ado Bryan and ask me what I knew about this
crime.
I know 60 years later, new leads are still emerging.
To me, an award-winning journalist, that's the making of an incredible story.
And on this podcast, you're going to hear it told by one of America's greatest storytellers.
Well, ask who had the motive to assassinate a sitting president.
My dad, the father of JFK, screwed us at the Bay of Pigs, and then he screwed us after the Cuban Missile Crisis.
We'll reveal why Lee Harvey Oswald isn't who they said he was.
I was under the impression that Lee
was being trained for a specific operation,
then we'll pull the curtain back on the cover-up.
The American people need to know the truth.

But then I met her. The name's Anna.
Hey, Anna, I'm Nico.
Didn't realize you were a professional musician.
From interval presents, a new romantic thriller podcast,
starring Jason DeRulo and Alexandra Ship.
There's something about you that I haven't been able
to look away from.
Nico, we don't even know each other.
Let's no turn it back if we do this.
I've already made my decision.
This is what happens when you don't follow orders.
Nicholas.
No!

I'm shaking
a little less.
I am too.
But I won't fully relax for another 15 to tang that.
10 to 15.
Hang in there. We'll get it.
All right. So what happened in the 1930s?
Oh, well, a guy named Dr. Lawrence. I can't remember, but he, the Lawrence livermore
laboratories named after him in part, invented particle accelerators where you use incredible amounts
of energy to throw trillions of particles of different weights or specific weights at
a target at them.
Tell them what Einstein, how Einstein described this process.
Like shooting birds in the dark in a country where there are only a few birds.
Right.
Like the chances of you actually having a collision are so remote that you, like they're
almost indescribable mathematically.
But if you shoot trillions of particles, you really increase your chances of there being
some kind of collision.
And when you collide a one particle, one atom with another atom, with enough energy, they
can combine.
And when you add proton to proton, remember, you get a new element.
And so with particle accelerators, they were able to start creating elements that you
can't find in nature.
And they started doing this all the way back in the 1930s.
And this research is what actually directly led to nuclear bomb.
Apparently, when Einstein heard that Lawrence had created this particle accelerator, he advised
FDR to start working on a bomb because it was now a thing.
Like, the world had just been prepared scientifically for a bomb to exist soon.
Yeah. scientifically for a bomb to exist soon. Yeah, so lab created elements, like you said, started being a thing
in 1937, anything past uranium on the chart,
you cannot find in nature because it decays much too fast
to even be around and know what's a thing in study.
But so anything past uranium is lab created and in 1937, tech, tech
netium was the very first blank spot to be filled in with a lab-created element
as number 43. Nuclear bombs that you mentioned when they started doing the, you
know, nuclear tests out on the Marshall Islands in the 50s, they would send planes out into these explosions
with filters on them to scoop up unusual atoms
and discover potentially elements.
That is how we got element 99 named Einsteinium.
And I guess we should talk a little bit about the naming
because the IUPAC actually has rules around this.
It says new elements
have to be named after a, and this is very interesting, a mineral, a place or a country,
a property, or a scientist, or a mythological concept, which is fascinating. So we have
some of the latest elements, I believe in 2016, is when we got 113 through 18. We got the element, Tennessee, because it was, there were institutions in Tennessee that
led to the discovery of this super heavy element.
And so they named it Tennessee.
And most of them sort of follow that naming convention.
Yeah, Nihonium is named after Nihon, which is the Japanese name for Japan.
A muskovian is named after Moscow,
where the lab where that was created.
In a Ganneson, Oganeson, Oganeson?
Oganeson?
Yeah.
That's what it is.
It's named after a guy named Yuri Oganesian,
who is a Russian essentially element hunter now.
He has got tons of funding behind him,
has set up new particle accelerators with more and more energy
and is bashing things together in the search for
entirely new elements that not only don't exist on Earth,
they may not exist anywhere else in the universe.
They may not exist anywhere else in the universe. They may only exist theoretically until Oganesean manages to smash the right atoms together
to create those elements for a picosecond.
Like, they're so unstable that they last almost no time at all, which makes them totally useless to us.
Yeah, as of now.
The fact that, like you said, they predicted, I think it's going to go up to 173.
And we're at 100 in what?
18.
Makes people like Ognesian, just crazy. They want to find them all.
And he actually found a couple of those most recent ones that were
inducted, I guess, in the periodic table in 2016.
Yeah. And this is kind of cool too.
Oganessian apparently wanted to name that element star dust
in honor of David Bowie, but it didn't fit the naming criteria.
Oh, yeah. Yeah.
Too bad. So sad.
Yeah. Too bad. So as far as the sort of the the Coda on this, Libby is keen to point out that there are gaps in the framework still.
There are issues when you look at the periodic table, you needn't only look at the very first one, hydrogen, at the far left of the table. It's there because as that one electron, but it is not like any of the rest of its group because the rest of them are all
alkali metals
It's actually more similar to something like chlorine, which is in the second column from the right
But you know, there's still debate on like
It's not settled on where things should be placed on these various and there have been you know
They're alternative tables that people have put out over the years with different tweaks, some small, some large, and it's pretty interesting,
I think.
And there's also that two period section that's always removed from the rest of the periodic
table and it's put down below it.
Those two sections actually go in...
That's the F block, right?
Yeah. The bottom two rows. So they come after I think
barium and just go all the way over to, oh, I can't remember the other one, but imagine that the
periodic table was looked like it did, but then the bottom two rows were about twice as long as
they are now. It looked weird. and it's because you would take that
lower F block and put it into its proper place
if you're arranging these things by atomic number.
But the reason why the F block is pulled out
is because those two rows of elements,
the actinides and lathinides, I think,
they may like follow an atomic number in that way, but their properties
are totally different from their periods or their groups. And the reason why is because
they're the only two groups that have the F position, sub shell, filled by an electron,
which completely alters their everything. It's just different than all of the other ones.
And it's different enough that they just basically removed it
until they can figure out where it should sit,
because depending on how you interpret
where like how the periodic table should be laid out,
they should go here or they should go there,
or they should just stay out like they are now.
Yeah, there are some, and it's kind of fun
to look some of these up if you want to see some kind of cool,
the very least just aesthetic examples.
And then they're not just like, oh, this looks cooler.
It makes sense to the person who has put out this
whatever alternative or alternate periodic table
like in 1949, Livy, I found one from Life magazine
that is a spiral and they're quite a few
different spiral or Sparillic designs where you have Hydrogen at the center and it's sort
of like racetrack shape. If you look at any, just look up spiral-based periodic chart
and they're very nice to look at. I imagine they're much, much harder to sort of make sense of and read unless you're the
person who made it.
Or a chemist.
Yeah, chemist would still probably be like, well, why are you doing it that way?
I like to see other way.
Or that 3D one that Timothy Stowe came up with that I think physicists are pretty keen on that has three axes of different colors
that represent quantum numbers that describe the electrons.
But if you look at a 3D version, that's kind of cool too.
But if you find the one, the traditional one confusing as a non-chemist, just try looking
at any of these other ones, it's really confusing.
Yeah.
And it's all it is, is it saying,, actually, no, I think we should arrange them so
that they're connected more by this property, like electro negativity or the shiny, or they're
pretty.
I like these elements, and we're so we're going to put them together.
These are my favorite elements.
It's just kind of like that.
And so you commend them in all sorts of weird shapes.
Yeah, I have my own periodic table I've designed.
Oh, yeah.
And it is just a big black block.
And then Times New Roman and Yellow lettering in the middle
it says, who gives a S?
Right.
I would have imagined it was a traditional periodic table,
but scratched out with a pen, not as violently.
No, that's good.
I like it better.
I'm going to change mine.
I've got one other thing that doesn't, it has a lot to do with everything, with a pen, not as violently. No, that's good. I like it better. I'm going to change mine.
I've got one other thing that doesn't,
it has a lot to do with everything,
but not anything we're going to go into,
but there are some, especially those elements
that don't occur in nature,
and they have to create and particle accelerators.
But also some that occur in nature,
like gold and mercury, or two good examples,
they have electrons that spin so fast that are
moving it such incredible energies that they actually are like a significant fraction of the
speed of light. That's how fast they're going. And it doesn't matter whether you're talking about
like a photon or a planet or a black hole or an electron, anything that has mass and can move
anything like half the speed of light is going to actually bend time and space. And so for some
kinds of elements that have relativistic speeds, meaning their electrons travel close to the speed
of light, they have all sorts of freaky-deaky
properties. It's why gold is gold. I'm not going to get into that. Just trust me, it's why gold is gold. But also it means that if you could go into those atoms and just kind of exist in them as
if they were a universe, you would see that the time and space was bent compared to how time and space exists outside of those
atoms, like on our level.
That's what atomic scientists have figured out, and it's actually kind of having a mind-breaking
effect on the periodic table to an extent.
Uh, amazing, I think so too.
That's it Chuck, we did periodic tables, it's done.
You did great.
Oh boy, we don't have to do it again? No, I don't think so. Got it, hope not. That's it Chuck, we did periodic tables, it's done. You did great. Oh boy, we don't have to do it again?
No, I don't think so.
I hope not.
What is this Murphy's Law?
Well, since I said Murphy's Law and Chuck laughed because he got the joke,
you may not have him, that's okay.
That means it's time for listener mail.
Alright, I'm going to call this very quick follow-up from our Halloween episode.
As we record this, it is actually Halloween.
So that has just come out today.
And we have something from Owen that perhaps explains something that we kind of wondered
about.
Hey guys, once again loving the yearly spooktacular, figured I'd mention my take on
what the Hermit meant. Hermit?
Hermit meant when he said the man's eyes didn't match his mouth.
I think it might have something to do with honesty like the words of encouragement
were somehow disingenuine.
That lined up with the idea that the hermit is sort of seeing flaws and faults.
That makes sense to me.
I said match his mouth.
It's like the best explanation I've heard so far.
It's also the only explanation, but it's a good one. I think it's totally it and Owen says regardless of whether that's the authors intent
I'm using the description in a song I'm writing. Oh cool
So thanks for the inspiration and in all honesty the voice work is on point this year
That is from Owen
Thanks a lot Owen. Here's a here's some inspiration for the musical part of your song.
