Explain why ionic compounds are formed when a metal bonds with a nonmetal but covalent compounds are formed when two nonmetals bond.

(1) Answers

Two nonmetals have enough electrons to share some for completing, so the bonds are covalent. A metal doesn't have that much, so it gives the few electrons on its outer layer more easily than a nonmetal (there must be a nonmetal to get them). This bond is ionic. I'm still unaware of possible bonds between 2 metals (are there any? :) )
