xenon

Also known as Xe, element 54, 54Xe

Xenon is a chemical element; it has symbol Xe and atomic number 54. It is a dense, colorless, odorless noble gas found in Earth's atmosphere in trace amounts. Although generally unreactive, it can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate, the first noble gas compound to be synthesized.

AI overview

Xenon is a rare, colorless, odorless gas found in Earth's atmosphere that belongs to a group of elements called noble gases, which are generally very unreactive. It became scientifically significant when researchers discovered that xenon could actually form chemical compounds, challenging the long-held belief that noble gases could never react with other elements.

Xenon is used in flash lamps and arc lamps, and as a general anesthetic. The first excimer laser design used a xenon dimer molecule (Xe2) as the lasing medium, and the earliest laser designs used xenon flash lamps as pumps. Xenon is also used to search for hypothetical weakly interacting massive particles and as a propellant for ion thrusters in spacecraft.
