- n. A colorless, odorless, highly unreactive gaseous 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 -111.9°C; boiling point -107.1°C; density (gas) 5.887 grams per liter; specific gravity (liquid) 3.52 (-109°C). See Table at element.
Century Dictionary and Cyclopedia
- n. 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.
- n. A heavy, gaseous chemical element (symbol Xe) of the noble gases group with an atomic number of 54.
GNU Webster's 1913
- n. (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 Xe (formely also X); atomic number 54; atomic weight 131.3.
- n. a colorless odorless inert gaseous element occurring in the earth's atmosphere in trace amounts
- From Ancient Greek ξένον, neuter of ξένος (xenos, "foreign, strange"). (Wiktionary)
- From Greek, neuter of xenos, foreign, strange; see xeno-. (American Heritage® Dictionary of the English Language, Fourth Edition)
“While krypton has a considerable vapour pressure at the temperature of boiling air, the vapour pressure of xenon is hardly appreciable; hence their separation, although tedious, presented no particular difficulty.”
“The word Xenon comes from the Greek word xenon which means stranger it was discovered by Sir William Ramsay in 1898.”
“The word Xenon comes from the Greek word xenon which means stranger it was discovered by Sir William Ramsay in 1898. has an Atomic Number of 86, the Atomic Symbol Rn, and the Atomic Mass of 222. 018g / mol.”
“I’ll be using a Nokia N82, which has an amazing 5-megapixel camera, brilliant in every sense of the word xenon flash and built-in GPS.”
“Now, it's important to note this gas, it's called xenon 133.”
“The radioactive gas xenon, which is often the byproduct of unexpected nuclear fission, was detected at the Fukushima Daiichi plant during tests.”
“Tepco said it may have found xenon, which is associated with nuclear fission, while examining gases taken from the reactor, according to an e-mailed statement today.”
“Nuclear explosions produce an excited form called xenon-133m, in which the atomic nucleus is boosted to a higher-energy state, but it is not known exactly how sensitive detectors are to this form because there has been no way to make pure samples of xenon-133m with which to test them.”
“Nuclear explosions produce an excited form called xenon-133m, in which the atomic nucleus is boosted to a higher-energy state.”
“Researchers at the national lab in Richland earlier worked on ways to detect radioactive xenon, which is released during nuclear explosions.”
