Definition:
Nitrogen (N) is the most abundant constituent of the atmosphere (78.09%).
Nitrogen enters the atmosphere from volcanoes, and from the decay of organic
matter. It is removed from the atmosphere by nitrogen-fixing bacteria. Nitrogen
compounds are very reactive and play integral roles in the production and
destruction of ozone in the atmosphere.
