Between metals and nometals

• Ionic Bonds

• Covalent Bonds

• Both bonds

• Neither bond

Atoms are most stable when their outer shell is complete.

• true

• false

Why do bonds form?

• To fill the valence shell of electrons for the elements involved

• to release energy stored in the bonds

• because whenever you mix two chemicals, there will be a reaction

• because of attraction

A bond between a metal and a nonmetal is called a(n)

• covalent bond

• ionic bond

• metallic bond

• transfer bond

Identify the following compound as ionic, metallic or covalent: MgO

• ionic

• covalent

• metallic
