My word....

Explanation:

You gots NO3..and a Lewis structure of this anion would be of the form of …O=+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, SO24, perchlorate, ClO4, and biphosphate, HPO24...
