Definition of xenon in US English:

xenon

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.

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

Origin

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