We use polyatomic ions a lot, so I think it will help to memorize the ones we use the most. For the following, I will either give you the name or the formula. You will supply either the name or formula, and the charge. For hw, give the formula and charge of these ions. This will be hw, and you will have a quiz on these. There will be monatomic ions also. You will use a pt without names. (Hint: be sure to know the symbols for lead and tin)
