amidogen

1. (inorganic chemistry, dated) The amino radical, •NH₂, the neutral form of the amide ion −NH₂⁻, regardable as the ammonia molecule with one of its hydrogen atoms removed.Examples: "."; "Chemical formulae: NH₂, *NH₂,\dot{}NH₂, \dot NH₂, NH₂*"; "1858, John Joseph Griffin, The Radical Theory in Chemistry, John Joseph Griffin, page 219, According to this theory, azote, in the presence of sufficient radicals, exercises its prerogative of producing amidogens and ammoniums, which then form salts with oxidised carbon, with negative hydrocarbons, or with any other acid radicals, oxidised or not oxidised, which are placed within its reach. But neither amidogens nor ammoniums are produced in the absence of negative radicals with which they can form salts."Synonyms: amido group, amido radical, amino radical, aminyl radical, azanyl radical, dihydridonitrogendated
