You probably know that all stuff is made up of atoms

is a really, really, really, really tiny particle.

some number of neutral particles called neutrons.

by negatively charged particles called electrons.

only by the number of protons in its nucleus.

Hydrogen is hydrogen because it has just one proton,

We can't see protons, neutrons, or electrons.

and develop a model for what we think is there.

If they don't, it might be time for a new model.

We've had lots of very different models for atoms

The cores of atoms tend to stick together,

They appear to behave either as particles,

depending on the experiment that we perform.

One of the weirdest things about electrons

is that we can't exactly say where they are.

It's not that we don't have the equipment,

But we can say there's a certain probability

And that means that we can ask the following question:

of finding a given electron within that shape,

Past a certain distance from the nucleus,

which means that while it will approach zero,

there is some small, but non-zero, probability

that for a very, very short period of time,

is at the other end of the known universe.

But mostly electrons stay close to their nucleus
