Electron Configuration

Nitrogen (N) is a chemical element with atomic number 7. Its most common isotope is 14N (7 protons and 7 neutrons). At standard temperature and pressure (STP), nitrogen exists in the form of nitrogen gas (dinotrogen, N2).

Nitrogen gas makes up 78% of the air we breathe on Earth.

Together with hydrogen, nitrogen makes up the chemical compound Ammonia, NH3, which is used as a fertilizer in agriculture.
