  krypton
  Symbol: Kr
  Atomic number: 36
  Atomic weight: 83.80
  Colorless gaseous element, belongs to the noble gases. Occurs in the
  air,
  0.0001% by volume. It can be extracted from liquid air by fractional
  distillation. Generally not isolated, but used with other inert gases in
  fluorescent lamps. Five natural isotopes, and five radioactive isotopes.
  Kr-85, the most stable radioactive isotope, has a half-life of 10.76
  years and is produced in fission reactors. Practically inert, though
  known
  to form compounds with fluorine.
