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] From The Collaborative International Dictionary of English v.0.48 [gcide]: Azote \Az"ote\ (?; 277), n. [F. azote, fr. Gr. 'a priv. + ? life; -- so named by Lavoisier because it is incapable of supporting life.] Same as {Nitrogen}. [R.] [1913 Webster] From The Collaborative International Dictionary of English v.0.48 [gcide]: Azote \A*zo"te\, n. [Sp.] A switch or whip. [Sp.
