Gas abundante en la corteza terrestre, constituye las cuatro quintas partes del aire atmosférico en su forma molecular N2, y está presente en todos los seres vivos. Inerte, incoloro, inodoro e insípido, se licua a muy baja temperatura. Se usa como refrigerante, en la fabricación de amoniaco, ácido nítrico y sus derivados, explosivos y fertilizantes. (Símb. N).

English
natron + -gen: cf. F. nitrog[`e]ne. See {Niter}.] (Chem.) A colorless nonmetallic element of atomic number 7, tasteless and odorless, comprising four fifths of the atmosphere by volume in the form of molecular nitrogen ({N2}). It is chemically very inert in the free state, and as such is incapable of supporting life (hence the name {azote} still used by French chemists); but it forms many important compounds, such as ammonia, nitric acid, the cyanides, etc, and is a constituent of all organized living tissues, animal or vegetable. Symbol N. Atomic weight 14.007. It was formerly regarded as a permanent noncondensible gas, but was liquefied in 1877 by Cailletet of Paris, and Pictet of Geneva, and boils at -195.8 [deg] C at atmospheric pressure. Liquid nitrogen is used as a refrigerant to store delicate materials, such as bacteria, cells, and other biological materials. [1913 Webster +PJC]
