4. Ionic Compound w/ Polyatomic Ion
Has 3 or more elements in the formula
at least one metal and at least one non - metal
• metal is written first - If it is a transition metal, include a Roman Numeral

6. Binary Molecular Compounds
Has two non - metals
• Write the names of the elements in the order they appear in the formula (least electronegative element should be written first)
• Change the ending of the second element to -ide
• use prefixes if there is more than 1 atom of a particular element
• Second element will always have a prefix
