Nitrogen was discovered in 1772 by Daniel Rutherford who called it "noxious air" or "fixed air".
Antoine Laurent de Lavoisier isolated it in 1786.
The name nitrogen comes from Latin "nitrogenium", where "nitrum" (from Greek nitron) means "saltpetre", and "genes" means "forming".
Nitrogen is an inert gas with many industrial applications. It is liquefied by cooling at -320.8 °F (-196 °C/77.15 K).
It is mainly found in the atmosphere, where it accounts for 78 % by volume of the air we breath. But nitrogen is also found in the Earth's crust (to a limited extent: in the form of nitrates, etc.), in organic form (in the living or dead plants and organisms), in mineral form (ammonia), thus contributing to soil fertility. In gaseous form, nitrogen is a neutral and colorless gas.
