 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.
