This is a little program I created for my Chemistry 9 midterm. It lists the polyatomic ions our teacher gave us. This may be useful to you, for whatever reason. It lists ions with +1, +2, -1, -2, and -3 charge, and not all of them. You are free to distribute and edit this program under the terms of the license provided. You may put either the protected version or the unprotected version on your calculator depending on what you prefer.
