# 1s^2 2s^2 2p6#

Explanation:

Nitrogen has an initial electron configuration of # 1s^2 2s^2 2p^3#
If Nitrogen gains three electrons the #2p# orbitals will have 6 electrons giving # 2p^6# This creates the electron configuration of Neon making the atom much more stable than the initial or ground state.

The 3 2p orbitals in the ground state have only one electron which can be used to create 3 electron sharings ( chemical bonds) . When all three chemical bonds are formed Nitrogen has three extra electron (#e^(-3)# )

The resulting electron configuration is # 1s^2 2s^2 2p^6#
