Main Question or Discussion Point

What happens to electrons at 0 Kelvin?
I know in theory all atomic motion stops (vibrational energy = 0),
and that the electrons occupy the lowest energy levels.
But it seems the electrons would have to still be orbiting or occupying non-localized states, and thus have kinetic energy? Can they have kinetic energy at 0 Kelvin?

That is not right. The atoms are in their ground state, in the lowest energy levels (but not zero), similar to the electrons.

Can they have kinetic energy at 0 Kelvin?
They can, and they have.

They can, and they have.
Does this derive from the Heisenberg uncertainty principle?

It is related to that, right.
