Ni`tro*gen, n. Etym: [L. nitrum natron + -gen: cf. F. nitrogène. See
Niter.] (Chem.)
Definition: A colorless nonmetallic element, tasteless and odorless,
comprising four fifths of the atmosphere by volume. It is chemically
very inert in the free state, and as such is incapable of supporting
life (hence the name azote still used by French chemists); but it
forms many important compounds, as ammonia, nitric acid, the
cyanides, etc, and is a constituent of all organized living tissues,
animal or vegetable. Symbol N. Atomic weight 14. It was formerly
regarded as a permanent noncondensible gas, but was liquefied in 1877
by Cailletet of Paris, and Pictet of Geneva.
