    • n krypton A chemical element, one of the five recently discovered gaseous constituents of the atmosphere, first obtained by Ramsay and Travers in 1898. It is colorless, transparent, without observable taste or smell, of density 40.88 as compared with hydrogen, liquefiable at—151.7° C. under atmospheric pressure, and occurs in the atmosphere to the extent of but 1 volume in 20,000,000 volumes of air.
