7. Polyatomic ions combine in a similar way as the monatomic ions in that the charges must sum to zero. The only difference is that if more than one polyatomic ion is needed, a parenthesis is used and the subscripts are placed outside the parentheses. Write the formula of the compound formed by combining the following ions. Use the ion cut outs to help as needed. NO3 SO,2- PO43- NHạ+ Mg2+ Al3+
