Leak! Leak!

Helium.

And this is just the configuration for helium.

And unfortunately, the helium atoms in liquid helium are right on top of each other.

An American Oil Spill

If it leaks

Let me take helium out of the picture.

Hydrogen has one proton, helium, two protons,

And now you see that helium, you get 1s and then you get 2s, so helium's configuration is

And unfortunately, the helium atoms in liquid helium are right on top of each other.

A helium atom has two protons and two neutrons.

But then all of a sudden, helium is a lot more stable.

And that's why helium's called helium.

Not all of it, a lot of it has been turned into energy, but most of it is now in helium.

And then this whole haze around there, those are the two electrons that helium has, or that at least this helium atom has.

Ooh. Check your hoses.

RSW Did it leak?

Do you realize if this ever leaked out...

Actually, let me take helium out of the picture.

Helium splits out, and a neutron comes out and lots of energy comes out.

This is the scale of the nucleus of a helium atom, right?

It's very hard, but a little easier than helium.

And as we have more and more helium the core becomes more and more dense because helium is a more massive atom.

We need helium, and the helium is what we really need to go deep.

Anyway, this is a depiction of a helium atom.

And now simple atoms appear of hydrogen and helium.

If it leaks Bilbao did not leak.

Engine seals check. Oh, God. Oh!

Testing, testing. One, two, three, four.

Water restriction tests, protein bond tests, eye tests, blood cultures...

In the middle of stars, you're joining hydrogen together to make helium and then helium together to make carbon, to make oxygen, all the things that you're made of are made in the middle of stars.

This is late in the life of a star in its giant phase.

For a moment they become helium 5, because they've got five particles inside them.

Or at least this helium atom has two protons and two neutrons.

In the case of helium, the nucleus is even a smaller fraction.

Helium has 2 protons. Carbon has 6 protons.

The first one was that when helium atoms touch each other, they repel.
