     neut. of krypto`s hidden.] (Chem.)
     An inert gaseous element of the argon (noble gas) group, of
     atomic number 36, occurring in air to the extent of about one
     volume in a million. It was discovered by Ramsay and Travers
     in 1898. Boiling point, -152.3[deg] C.; melting point,
     -156.6[deg] C.; symbol, Kr; atomic weight, 83.8.

  krypton
       n : a colorless element that is one of the six inert gasses;
           occurs in trace amounts in air [syn: {Kr}, {atomic number
           36}]

From Elements database 20001107 [elements]:

  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}.
