Facts about xenon

Here are a few interesting facts about xenon element.

  1. Xenon was given its name from the Greek word “xenos” which means stranger.
  2. Xenon gas is 4 times heavier than air.
  3. Xenon is very rarely available and so it is a very expensive noble gas.
  4. The concentration of xenon in the earth’s atmosphere is only 1 part per 20 million.
  5. Mars’s atmosphere also contains xenon in the concentration of 0.08 ppm.

Properties of xenon

Here is a list of some physical properties and chemical properties of xenon.

Physical properties of xenon

  • Xenon is a colorless, odorless and tasteless gas.
  • The solidified xenon gas appears light blue in color.
  • Xenon has FCC crystal structure.
  • Xenon glows with blue (or lavender) light when it is subjected to electrical discharge.
  • The melting point and boiling point of xenon is -111.7 °C and -108 °C respectively.

Chemical properties of xenon

  • Xenon has 8 valence electrons and this indicates that it has a stable octet.
  • The electron configuration of xenon is [Kr] 4d10 5s2 5p6 and the electron shell arrangement is 2, 8, 18, 18, 8.
  • Xenon is chemically inert but it shows a chemical reaction with some highly reactive elements like fluorine.

Uses of xenon

Here are some uses of the xenon element.

  • Xenon is used in flash lamps as well as stroboscopic lamps because it gives a blue or lavender light on electrical discharge.
  • Xenon is also used as an anesthetic gas in medical applications.
  • Xenon gas is also used in TV tubes.
  • Xenon is also used in headlights of vehicles (which gives a bluish glow).
