Definition of xenon in English:



mass noun
  • 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.

    • ‘We've also lost other gases like nitrogen, xenon, krypton - they've all been lost from the atmosphere.’
    • ‘For visible-light applications using halogen or xenon lamps, an aluminum-silicon-oxide coating is also available.’
    • ‘As the Earth rotates, these orientations change and the small difference between the helium and xenon frequencies would therefore change with time.’
    • ‘It doesn't matter what the club is made of - wood, steel, graphite, titanium, xenon, ytterbium or zirconium.’
    • ‘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.’
    • ‘They attributed those lines to the presence of three new elements, which they named neon, krypton, and xenon.’
    • ‘A Lo255 Oriel xenon lamp was employed as detecting light source.’
    • ‘Krypton and xenon also find commercial lighting applications.’
    • ‘A cathode emits a stream of electrons that collides with neutral atoms of xenon, a gaseous element, in a chamber.’
    • ‘In the same year, Ramsay and Travers discovered two other noble gases, xenon and neon.’
    • ‘A plasma monitor often consists of two panels, which are filled with an inert gas, such as xenon or neon.’
    • ‘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.’
    • ‘He estimates future conversion efficiencies of several percent with tin, whereas xenon has a 1% limit.’
    • ‘Plus, xenon happens to be a noble gas, which means it won't corrode or otherwise interact chemically with anything.’
    • ‘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.’
    • ‘A 250 W xenon arc lamp and a mechanical chopper provided the analyzing beam.’
    • ‘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.’
    • ‘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.’
    • ‘Along with helium, neon, argon, krypton, and xenon, it is classed as an inert gas within group 0 of the periodic table.’
    • ‘In the early 1960s, a number of chemists found ways of making compounds of some noble gases, including radon, xenon, and krypton.’


Late 19th century: from Greek, neuter of xenos ‘strange’.
