Nitrogen is a diatomic, inert gas making up about 78% of Earths atmosphere and is central to biological and industrial cycles.
Properties of Nitrogen | It is colorless, odorless and relatively inert at ambient conditions but forms reactive compounds under activation.
Uses of Nitrogen | Nitrogen is used to produce ammonia for fertilizers, as an inert atmosphere in manufacturing and in cryogenics as liquid nitrogen.
Isotopes of Nitrogen | Stable N 14 and N 15 exist; nitrogen asphyxiation is a hazard in confined spaces when oxygen is displaced by inert gas.
