Q
Formulas for ionic compounds
A
- Write the symbol for the metal cation and its charge then the symbol for the nonmetal anion and its charge
- adjust the subscript on each cation and anion to balance the overall charge
- check that the sum of the charges of the cations equals the sum of the charges of the anion

Q
Naming Molecular Compounds
A
- prefix + name of 1st element
- prefix + base name of 2nd element +ide
-first name the metal element; element with the smaller group number first; if they are in the same group -> element with the greater row number first
