Heisenberg got it wrong!

The reason you can't know both the location and movement of an electron
on an atom is because the electrons are everywhere at once, so they appear
to be a solid shell. This is because the electrons are travelling as energy
at the speed of light. If we could see an atom of, say Gold, we would see a
little ball of gold. The number of electrons and the number of shells impart
shape, appearance and weight to an atom, and to molecules where the shells
of the constituent atoms merge into one shell surrounding the molecules.
