Answer:

My word....

Explanation:

You gots #NO_3^(-)#..and a Lewis structure of this anion would be of the form of …#O=stackrel+N(-O^(-))_2#...the nitrogen is quaternized and BEARS a formal positive charge....and TWO of the oxygen atoms bear a formal negative charge. The overall charge of the ion is #-1#, and all the oxygen atoms are equivalent by resonance.

Other examples of polyatomic ions include sulfate, #SO_4^(2-)#, perchlorate, #ClO_4^(-)#, and biphosphate, #HPO_4^(2-)#...
