What is the octet rule of nitrogen?

The octet rule is the understanding that most atoms seek to gain stability in their outer most energy level by filling the s and p orbitals of the highest energy level with eight electrons.

Nitrogen has an electron configuration of #1s^2 2s^2 2p^3# this means that nitrogen has five valence electrons #2s^2 2p^3#. Nitrogen seeks out three additional electrons to fill the p orbital and gain the stability of a noble gas, #1s^2 2s^2 2p^6#.

However, now nitrogen has 10 electrons and only 7 protons making it a -3 charge anion #N^(-3)#.

I hope this was helpful.
