ni·tro·gen

 (nī′trə-jən)
n. Symbol N
A nonmetallic element that constitutes nearly four-fifths of the air by volume, occurring as a colorless, odorless, almost inert diatomic gas, N2, in various minerals and in all proteins and used in a wide variety of applications, including manufacture of ammonia, nitric acid, TNT, and fertilizers, and as a cryogen. Atomic number 7; atomic weight 14.0067; melting point -210.00°C; boiling point -195.80°C; valence 2, 3, 4, 5. See Periodic Table.

[French nitrogène : nitro-, nitric acid (from New Latin; see nitro-) + -gène, -gen.]

ni•tro•gen

(ˈnaɪ trə dʒən)

n.
a colorless, odorless, gaseous element that constitutes about four-fifths of the volume of the atmosphere and is present in combined form in animal and vegetable tissues, esp. in proteins. Symbol: N; at. wt.: 14.0067; at. no.: 7; density: 1.2506 g/l at 0°C and 760 mm pressure.
[< French nitrogène (1790); see nitro-, -gen; so named from its presence in nitric acid]

ni·tro·gen

(nī′trə-jən)
Symbol N A nonmetallic element that makes up about 78 percent of the atmosphere by volume, occurring as a colorless, odorless gas. It is a component of all proteins, making it essential for life, and it is also found in various minerals. Nitrogen is used to make ammonia, nitric acid, TNT, and fertilizers. Atomic number 7. See Periodic Table. See Note at oxygen.
