The full electron configuration for nitrogen is #"1s"^ 2"2s"^2"2p"^3#.

The noble gas shorthand electron configuration is #["He"]"2s"^2"2p"^3"#.

Explanation:

The atomic number of nitrogen is 7. This is the number of protons in the nuclei of nitrogen atoms. A neutral atom has the same number of electrons as protons. So the electron configuration will include 7 electrons placed into the appropriate s and p orbitals in the ground state (state of lowest energy).
