Answer:

There are 17 valence electrons to distribute around 3 centres........

Explanation:

And the 17 valence electrons come from the #5+2xx6# oxygen, and nitrogen valence electrons.

So a reasonable Lewis structure is #(O=)N^(+)-O^-# with a LONE nitrogen-centred valence electron. These electrons can couple to form a #N-N# bond in a dimer.

#2(O=)N^(+)-O^(-)rightleftharpoons(""^(-)O)(O=)N^(+)-NO_2#

There is necessarily formal charge separation in both the monomer and the dimer.
