The chemical element of atomic number 54, a member of the noble gas series. It is obtained by distillation of liquid air, and is used in some specialized electric lamps.
- ‘In the early 1960s, a number of chemists found ways of making compounds of some noble gases, including radon, xenon, and krypton.’
- ‘The problem with using xenon as a target material is that it is only liquid over a very small temperature range of four degrees, which has provided us with some interesting challenges.’
- ‘In the same year, Ramsay and Travers discovered two other noble gases, xenon and neon.’
- ‘They attributed those lines to the presence of three new elements, which they named neon, krypton, and xenon.’
- ‘He estimates future conversion efficiencies of several percent with tin, whereas xenon has a 1% limit.’
- ‘We've also lost other gases like nitrogen, xenon, krypton - they've all been lost from the atmosphere.’
- ‘All are present in the gas as the monatomic elements and argon, krypton, and xenon undergo condensation to either ices or clathrate hydrates at sufficiently low temperatures.’
- ‘A cathode emits a stream of electrons that collides with neutral atoms of xenon, a gaseous element, in a chamber.’
- ‘A 250 W xenon arc lamp and a mechanical chopper provided the analyzing beam.’
- ‘We're using our big laser system to study the detailed atomic physics of xenon with other alkalis besides rubidium, such as cesium and potassium.’
- ‘Plus, xenon happens to be a noble gas, which means it won't corrode or otherwise interact chemically with anything.’
- ‘It doesn't matter what the club is made of - wood, steel, graphite, titanium, xenon, ytterbium or zirconium.’
- ‘The presence of xenon in such lamps results in a very bright, sun-like light used in photographic flash units, strobe lights, and airport runway lights.’
- ‘It consists of a tube filled with xenon gas, with electrodes on either end and a metal trigger plate at the middle of the tube.’
- ‘Krypton and xenon also find commercial lighting applications.’
- ‘As the Earth rotates, these orientations change and the small difference between the helium and xenon frequencies would therefore change with time.’
- ‘Along with helium, neon, argon, krypton, and xenon, it is classed as an inert gas within group 0 of the periodic table.’
- ‘A plasma monitor often consists of two panels, which are filled with an inert gas, such as xenon or neon.’
- ‘A Lo255 Oriel xenon lamp was employed as detecting light source.’
- ‘For visible-light applications using halogen or xenon lamps, an aluminum-silicon-oxide coating is also available.’
Late 19th century: from Greek, neuter of xenos ‘strange’.
