Answer 1

Explanation:

Cations

Nonmetals form ______ Anions

The electrons that occupy the outermost energy level of an atom valence electrons

hope it helps

Answer 2

Explanation:

Metals lose electrons in bonding whilst non-metals gain electrons during ionic bonding hence metals form cations and non-metals form anions. It is difficult for a non metal such as oxygen to lose 6 electrons to form a cation since it would need a lot of energy. When it comes to metals it is also difficult to gain that much elecrons since as electrons are added the effective nuclear charge increases each time.
