And the proton is actually the defining

Atomic nucleus

You see these black dots? Those are the stable nuclides and all the other guys are radioactive.

Draw atomic nuclei

The quarks, these pink things, are the things that make up protons and neutrons that make up the atomic nuclei in your body.

Nuclear energy is produced by splitting atoms or by bringing them together.

So the atom is roughly on the scale of an angstrom.

It contains protons, neutrons and electrons.

One femtometer.

Think how many discoveries they represent.

And what defines each element is the number of protons in the nucleus.

One, two, three, four, five, six.

In which case, the nucleus... would be here.

But there is a majority in favor of the radiation scenario.

One, two, three, four, five, six.

Two nuclides are isotones if they have the same number N of neutrons.

But a first mental model in your head is at the center of this atom, of this carbon 12 atom, you have this nucleus.

And that's where it gets philosophically interesting.

They just have a probability function.

The most stable nucleus is iron, right in the middle of the periodic table.

We also all know that atoms are not the end of the story.

But that's a good starting point.

And these electrons are jumping around this nucleus.

There are a few nuclear bomb shelters in the city.

So imagine a ball that is as tall as a two story house.

Think atoms in a grapefruit like blueberries in the Earth.

And maybe something that looks like that.

You change the protons, you got a different element.

like this.

Now with that out of the way let's learn a little bit of Trigonometry.

Now that led to an understanding of atomic structure because the way that's explained is atoms are a single nucleus with electrons going around them.

And when I say stuff, that's a very abstract concept, because we're talking about the nucleus, right?

Number of particles

So we'll take it from first principles. Let's talk a bit about what nuclear fission is.

Its volume increases roughly by a factor of 1000.

Now look inside the blueberry, and blow it up to the size of a football stadium, and now the nucleus is a marble in the middle.

The gap is very tiny, and I've blown it up so you can see it.

According to the International Atomic Energy Agency, during the last year alone,

These baryons also bonded, forming nucleons.

Here, the predictions of the Big Bang nucleosynthesis in plot it in one diagram.

Here we have three factors.

What do you see there?
