200
Cations form when atoms _________ electrons, while anions form when atoms ___________ electrons.
lose, gain
200
Metals can form _________, and Non Metals can form ____________.
cations, anions
200
Atoms or cations, which are smaller? WHY?
Cations are smaller, they form when atoms lose electrons and lose shells.
