(Symbol Xe ) A noble gas, atomic number 54, atomic weight 131 3; a heavy, unreactive, colorless element found in the atmosphere to the extent of only 0 0000087% by volume
One of the noble gases, it is colourless, odourless, tasteless, and nearly inert, combining only with fluorine and oxygen and in complexes (see bonding). Xenon occurs in slight traces in Earth's atmosphere and in rocks. Obtained by fractional distillation of liquefied air, it is used in luminescent tubes (see electric discharge lamp), flash lamps, lasers, and tracer studies and as an anesthetic
The gas used in HID systems that produce the extreme white color Xenon gas is also used in some halogen bulbs to produce a whiter light and to keep deposits off the glass tube
A very heavy, inert gaseous element occurring in the atmosphere in the proportion of one volume is about 20 millions
An inert gas used as a component in certain lamps to produce a cooler color temperature than standard incandescent It is often used in applications where halogen may normally be specified, because of a longer lamp life
a colourless gas that is found in very small quantities in the air. It is a chemical element : symbol Xe (xenos (because it is rare)). Chemical element, chemical symbol Xe, atomic number
a crystalline substance, XeF2, used as a fluorinating agent and oxidizing agent in various surface modification processes, and as an etching agent in semiconductor production
