Pretty sure. I think this is why Van Der Waals forces get stronger with an increased number of electrons.

In all cases, yes. Since the e- repel each other, so more e- means more repulsion which pushes them further apart.

Take the simplest example: a H atom - 1 p+ and 1 e-
Give it a second e-, you now have 1 p+ struggling to hold onto 2e-, which are trying to get away from each other.
