So it is well for us that air is only a mixture of oxygen and nitrogen, and not a compound.
He was the discoverer of nitrogen and several gaseous bodies.
- a colourless odourless relatively unreactive gaseous element that forms 78 per cent (by volume) of the air, occurs in many compounds, and is an essential constituent of proteins and nucleic acids: used in the manufacture of ammonia and other chemicals and as a refrigerant. Symbol: N; atomic no: 7; atomic wt: 14.00674; valency: 3 or 5; density: 1/2506 kg/m³; melting pt: –210.00°C; boiling pt: –195.8°C

1794, from French nitrogène, coined 1790 by French chemist Jean Antoine Chaptal (1756-1832), from comb. form of Greek nitron "sodium carbonate" (see nitro-) + French gène "producing," from Greek -gen "giving birth to" (see -gen). The gas was identified in part by analysis of nitre. Earlier name (1772) was mephitic air, and Lavoisier called it azote (see azo-).
