Krypton: historical information

  • Discoveror: Sir William Ramsay, Morris W. Travers
  • Place of discovery: Great Britain
  • Date of discovery: 1898
  • Origin of name : from the Greek word "kryptos" meaning "hidden".

Krypton was discovered in 1898 by Sir William Ramsay and his student Morris Travers in the residue left after liquid air had nearly boiled away. Krypton was left in the residue after boiling away water, oxygen, nitrogen, helium, and argon from the sample of air. Krypton is present in the air at about 1 ppm. Neon was discovered by a similar procedure by the same workers just a few weeks later.
