Did you know?

  • 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.
