For the following species, draw a lewis structure for one important resonance form. include all lone pair electrons and assign formal charge to any atom with a non-zero formal charge
no2+
no2f (n is central)

The Lewis structures are shown in the figure

Explanation:

The lewis structure will be drawn using following steps

i) we will calculate the total number of valence electrons in the molecule

ii) will assign one bond (two electrons in between two atoms)

iii) then distribute the rest of the valence electrons as lone pair or shared pair based on completion of octet.

The structure of each molecule is given in the figure.

Valence electrons:

V.E = 5 +(2)6-1=16

V.E =5 +(2)6+7=24
