# What is the oxidation number for nitrogen?

Mar 13, 2014

Nitrogen has several oxidation numbers. However, the most common oxidation state is -3 or ${N}^{- 3}$

Nitrogen has as an electron configuration of
$1 {s}^{2} 2 {s}^{2} 2 {p}^{3}$

In order to satisfy the rule of octet the nitrogen atom will take on three electrons to become
$1 {s}^{2} 2 {s}^{2} 2 {p}^{6}$

In doing so Nitrogen becomes a -3 ion of ${N}^{- 3}$

I hope this was helpful.
