The term nitrogen was first used by J. A. Chaptal in 1790. This early "nitrogen" was later shown by John Strutt (Lord Rayleigh), and William Ramsay to contain argon; Henry Cavendish had shown in 1785 that there was an unreactive gas other than nitrogen
The Chemistry of Nitrogen and Phosphorous
The chemistry of nitrogen is dominated by the ease with which nitrogen atoms form double and triple bonds. A neutral nitrogen atom contains five valence electrons: 2 s 2 2 p 3 . A nitrogen atom can therefore achieve an octet of valence electrons by sharing three pairs of electrons with another nitrogen …
