Using Polyatomics

Tips!

Remember that you need parenthesis around the polyatomic ion’s formula if there’s more than one of them in the compound (to show there’s several of the entire group), but there are no parenthesis if there’s only one of them or around monatomic ions. In particular, watch out for hydroxide and cyanide….people forget the parenthesis on these two ions most frequently!!

Don’t forget, Webassign is due 10/30!
