    • n Xenon zĕn"ŏn; zē"nŏn (Chem) A very heavy, inert gaseous element of the noble gas group, occurring in the atmosphere in the proportion of one volume is about 20 millions. It was discovered by Ramsay and Travers in 1898. It can be condensed to a liquid boiling at -107° C., and to a solid which melts at -111.9° C. Symbol Xeformely also X); atomic number 54; atomic weight 131.3.

    • n xenon In chem., the heaviest of the five recently discovered elementary substances present in gaseous form in the atmosphere. It was first obtained by Sir William Ramsay, assisted by M. W. Travers, in 1898, as a result of the careful fractional distillation of liquid air. It is a colorless gas, of density about 65.35 (oxygen = 16), condensable to a colorless liquid of density 3.52 at its boiling-point (water = 1), which boils under normal pressure at —109.1° C. Xenon is incapable, as far as known, of chemically combining with anything else. It gives in a suitably exhausted tube by electrical discharge a characteristic spectrum, which is modified on introduction of a Leyden jar and spark-gap. Ramsay found in atmospheric air about 1 volume in 170,000,000 of air.
