How do charges help you decide subscripts? Look up the charges for each element (or polyatomic ion). Determine the least common multiple between the two charges. The factor each charge needs to be multiplied by to give the least common multiple will be the subscript for that element.

Ionic vs. Covalent Ionic compounds result from an exchange of electrons. When you have a metal bonding to a nonmetal they will exchange electrons. Covalent compounds result from sharing electrons. When you have a nonmetal bonding to a nonmetal they will share electrons.
