What is the electron configuration of nitrogen 3-?

Oct 27, 2016

$1 {s}^{2} 2 {s}^{2} 2 p 6$

Explanation:

Nitrogen has an initial electron configuration of $1 {s}^{2} 2 {s}^{2} 2 {p}^{3}$
If Nitrogen gains three electrons the $2 p$ orbitals will have 6 electrons giving $2 {p}^{6}$ 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 $1 {s}^{2} 2 {s}^{2} 2 {p}^{6}$
