Hi experts, I still do not understand how positive charge is distributed inside a conductor. In case of extra electrons is it quite evident, as they are free to move and repel each other, so they go as far away as they can. But what exactly happens if electrons are removed from a conductor, lets say by induction and grounding? I have already read that positive and negative extra charges are distributed on the surface, but how to describe the physics for the lack of electrons? Is there a tiny (one to two atoms) layer on the surface with no electrons? How to "feel" that this distribution has the least potential energy? Thank you in advance.
