Nitrogen, or N2, is a diatomic gas which comprises 78 percent of the earths atmosphere. In addition to air, nitrogen is found in the protein matter of all life forms, in some natural gas-hydrocarbon deposits, and in many organic and inorganic compounds.Colorless, odorless, tasteless, and nontoxic, nitrogen exists as a non-flammable gas at atmospheric temperatures and pressures. A specific gravity of .9669 makes nitrogen slightly lighter than air. When cooled to its boiling point of -320F, nitrogen becomes a colorless liquid which can, in turn, be compressed into a colorless, crystalline solid. It is only slightly soluble in water and most other liquids, and is a poor conductor of heat and electricity.
