What makes an electron “move” around an atom? Like what force actually propels it? What causes the motion?

Question

So an electron ‘moves’ around the nucleus of an atom. But what causes this motion? Is it just eternal inertia since the atoms founding?

And I don’t mean when elections change levels, I mean the actual motion of the revolution around the nucleus of the atom.

Thanks!

Quantum is weird. 

So the answer, at least partially is “it doesn’t”.

Electrons, like most particles, do not exist in any single point in space. That’s because they have wave properties too, it’s not just light.

The only thing that happens in a specific point in space is an interaction between particles. Otherwise they’re everywhere they CAN be, at the same time.

In the case of electrons around atoms, where they can be is in specific regions of space around the nucleus, their shape determined by the energy orbital they’re in.
