MEMORIZING:  You will only be quizzed on the polyatomic ions today.  If this website below works for you, it will be a little more entertaining way to study.  Select the 12 ions we've learned on the initial page (by clicking the stars), and then choose "scatter."  Before playing, click on the "12 star" button so you don't get all 22 of them.  If time permits, you can also try the space race.
