Yes, exactly. But my atom is uncharged sphere, I'll bring two similar size
and similar mass (+ -) ions inside the sphere. So rotation will not happen
then for atom.

In fact you are then creating a small molecule, like C=O. Nothing wrong
with that, but you are also creating particles with a mass, which means the
"atom" get rotational properties.
