n. Symbol Xe
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.
[From Greek, neuter of xenos, foreign, strange; see xeno-.]
(Elements & Compounds) a colourless odourless gaseous element occurring in trace amounts in air; formerly considered inert it is now known to form compounds and is used in radio valves, stroboscopic and bactericidal lamps, and bubble chambers. Symbol: Xe; atomic no: 54; atomic wt: 131.29; valency: 0; density: 5.887 kg/m3; melting pt: –111.76°C; boiling pt: –108.0°C
[C19: from Greek: something strange]
xe•non(ˈzi nɒn, ˈzɛn ɒn)
a heavy, colorless, chemically inactive, monatomic gaseous element used for filling radio, television, and luminescent tubes. Symbol: Xe; at. wt.: 131.30; at. no.: 54.
[1898; < Greek xénon, neuter of xénos strange (see -on2)]
Symbol Xe A colorless, odorless element that is a noble gas and occurs in extremely small amounts in the atmosphere. It was the first noble gas found to form compounds with other elements. Xenon is used to make lamps that make intense flashes, such as strobe lights and flashbulbs for photography. Atomic number 54. See Periodic Table.
