First step – memorize what you are supposed to memorize – polyatomic ions, rules, etc. Next, organize your notes into what you do for ionic compounds, those with metals and polyatomic ions, and what you do for molecules, those with only nonmetals and metalloids. Then analyze every single compound you have to name or write a formula for – is it ionic? then you only use the Stock system. Is it a molecule – then you can use the Stock system or prefixes. Do you see what I mean?
