An ionic bond can be formed when one or more electrons are?
(1) equally shared by two atoms
(2) unequally shared by two atoms
(3) transferred from the nucleus of one atom to the nucleus of another atom (4) transferred from the valence shell of one atom to the valence shell of another atom
I think the answer would be 4 because electrons are not located in the nucleus so it wouldn't be 3 and the valence electrons are the ones that are usually transferred and involved in chemical reactions
