C.. it wants to try to remain in a state of equilibrium or equal
with that being said it wants to electrons to be equal to the number of electrons as much as possible
its like static friction when you rub a balloon on your head... you are replacing electrons for neutrons and that why it can stick to a wall after you rub it on your head because a wall only has negative atoms and when you rub the balloon on your head it takes some positive and charges it up positively and attracts to the negative atoms on the wall
