Top 15 interesting facts about Xenon

  • Xenon was discovered in 1898 by Sir William Ramsay. Its name derives from the Greek word "xenon" which means "stranger".
  • Xenon's melting point is at -111.9 C (161.25 K, -169.42 F) and its boiling point is at -108.1 C (165.05 K, -162.58 F).
  • Xenon is colorless and odorless noble gas.
  • Xenon can be found in Earth’s atmosphere.
  • Xenon gas has a density 4.5 times greater than the density of the Earth's atmosphere at surface.
  • Liquid xenon has a density of 3100g/ml.
  • Solid xenon is heavier than granite.
  • Xenon emits blue-white glow when it is excited by electricity.
  • Xenon is obtained as a byproduct of oxygen and nitrogen production.
  • Xenon is an expensive gas (50 times more expensive than neon).
  • Jupiter contains large quantities of xenon.
  • Xenon has eight stable isotopes and over forty unstable isotopes.
  • Xenon is used in illumination and optics (xenon flash lamps, xenon arc lamps, night vision systems, plasma displays, lasers etc).
  • Xenon is also used in medical industry as a general anesthetic, neuro-protectant, dopant, tomography image, nuclear energy applications etc.
  • Xenon is a non-toxic gas, although it has harmful effects if inhaled in large quantities.
