If there is a positively charged rod,which is placed near an aluminium foil,free electrons in the foil are pulled towards the rod.This makes the top end of the foil negative and leaves the bottom end short of electrons to become positive.
I wonder if the rod has a very large positive charge(e.g.10+),will it be strong enough to pull the electrons in the aluminium away from the foil?
So the "remaining part" of the foil(which is positively charged ion) will either decompose due to its
enormous internal repulsive forces between ions(as there are no electrons) or attract electrons from the surroundings(e.g.air) so as to become electrically neutral?
Is it possible for a substance to have a high positive charge in solid state?
I hope someone will understand what I am saying :(,it seems to be nonsense.
