Legend

Name origin:	Greek: nitron and genes, (soda forming)
Description:	Colorless, odorless, tasteless, generally inert gas. Fifth most abundant element in the universe. Makes up about 78% of earth's atmosphere.
Discovered by:	Daniel Rutherford
Year:	1772
Place:	Scotland
Sources:	Obtained from liquid air by fractional distillation.
Use(s):	Primarily to produce ammonia and other fertilizers. Also used in making nitric acid, which is used in explosives. Also used in welding and enhanced oil recovery.
