Inorganic nitrogen falls into 3 categories Nitrogen hydrides, Nitrogen oxoacids, and Inorganic amines. Nitrogen fixation is a process by which nitrogen (N2) in the atmosphere is converted into inorganic nitrogen (ammonia NH3). Molecular nitrogen is inert it does not easily react with other chemicals to form new compounds. Fixation free up the nitrogen atoms from the diatomic form. The biological fixation of inert nitrogen is carried out mainly by free-living and symbiotic Diazotroph bacteria although fixation occurs in some lightning strikes.
