a heavy, colorless, gaseous chemical element, one of the noble gases, present in the air in minute quantities and found to react with fluorine and other reactive compounds and to form salts and acids in solution: used in bubble chambers, electric luminescent tubes, lasers, vacuum tubes, etc.: symbol, Xe; at. no. 54
Origin of xenonModern Latin from Gr, neuter of xenos, foreign, a stranger: so named (1898) by Sir William Ramsay and M. W. Travers (see krypton), as the hitherto unknown inert gas
A colorless, odorless, noble gas element found in minute quantities in the atmosphere, extracted commercially from liquefied air and used in stroboscopic, bactericidal, and laser-pumping lamps. Atomic number 54; atomic weight 131.29; melting point −111.74°C; boiling point −108.09°C; density (gas) 5.89 grams per liter; specific gravity (liquid, at −109°C) 2.95; valence 0, 2, 4, 6. See Periodic Table.
