There are two major resonance structures for #"NO"_2#.

You must first draw the Lewis structure for #"NO"_2#.

You find that you can draw two Lewis structures.

The #"N"# atom has an unpaired electron and a positive charge.

Every atom has a formal charge of zero.

These are the two major resonance contributors to #"NO"_2#.
