AP Chemistry Students:

    Imagine that you were marooned on a desert island....  You would need to know your......

Polyatomic ions!  

Learn the names, formulas and charges of the following ions as quickly as possible! 

           

            As you study the names and formulas of these ions, do the following:

    Keep in mind that these are charges particles composed of covalently bonded atoms, hence they have structures similar to molecular structures. 

   Look for patterns in the names and structures and charges of the different ions.  This will help you memorize them.  How consistent are these patterns?
