Question

draw the lewis structure for NO2. Include all necessary bonds, lone pairs of electrons ( or single unshared electrons if appropriate), and non zero formal charges.

Answer 1

In NO₂,   nitrogen has 5 valence electrons and each of the oxygen has 6 valence electrons.

So total number of valence electrons= 17

Now, we need to draw the lewis structure for NO2. Include all necessary bonds, lone pairs of electrons (or single unshared electrons if appropriate), and non zero formal charges.

The charge assigned to an atom in a molecule is it’s formal charge (FC) and it can be calculated by the following formula,

FC= V-N –B/2

Where, V= number of valence electrons

N= number of nonbonding electrons

V= number of electrons shared to covalent bonds

So the Lewis structure o NO2 along with formal charges will be as follows
