Why are Fe2+, S2-, and Fe3+ here? None of them are polyatomic ions. Also, you should remove the charges from the answer or write a proper description that says you have to type the charge of the ion too.

This quiz is for personal study use, and the course I am studying for includes these ions as well. Apologies for any confusion.
