So that's essentially just all there is to the difference between protons and neutrons.

It's

the combination of clerks they have.

Two ups and one down, or one up and two downs.

Alright, so now let's move on to the weak nuclear force, which is the third of our forces that we're going to be talking about today.

The weak nuclear force is probably the least well known and in some ways the hardest to it's not the most complicated because the strong is sort of harder to compute, but the weak can be harder to initially understand because it's um it behaves differently in certain ways.

So the weak nuclear force affects all particles that have

have a special quantum number called weak isospin.

And I won't try to explain intuitively what this is.

It's just another quantum number.

Don't get it confused with what we ordinarily call just spin.

All fermions have half integer spin.

Um but there's another a different quantum number called weak isospin, which varies between different types of particles.

Uh most of the f the the fermions

So that includes uh the electron, quarks, and also neutrinos, which are another um important type of particle that we'll we'll talk a bit more about in a moment.

So what does the weak force do?

We know the electromag one we know what the electromagnetic force does, and we know that the strong force keeps nuclei together.

What does the weak force do?

Well, it's a bit harder to explain because the weak force does not form any bound states.

So remember a bound state is sort of like a stable state with multiple particles joined together in a form that's sort of stable over long periods of time, uh like atoms and molecules for the electromagnetic force or hadrons and nuclei for the strong force.
