As the nearly unreactive diatomic molecule N2, it is useful as an inert atmosphere or to dilute other gases. Nitrogen is commercially produced by distillation of liquefied air. Nitrogen fixation, achieved naturally by soil microbes and industrially by the Haber-Bosch process, converts it to water-soluble compounds (including ammonia and nitrates).

它是最稳定的双原子分子N2，可用来产生惰性的气体氛围，或用于稀释气体。商业上通过液化空气的蒸馏来生产氮气。自然界通过土壤里的微生物可达成固定氮作用，而在工业上则利用哈伯-博施法将它转化成可溶于水的化合物(包括氨和硝酸盐)。
