After it has been stored a few days, krypton obtained by nuclear fission contains only one radioactive isotope, krypton-85, which has a half-life of 10.7 years, because all the other radioactive isotopes have half-lives of 3 hours or less. Krypton discharges a greenish yellow glow when it is mixed with other gases. The cationic species KrF+ and Kr2F3+ are formed in reactions of KrF2 with strong fluoride-ion acceptors such as the pentafluorides of Group 15, in which the fluoride ion F is transferred to the pentafluoride to give complex salts that are analogous to those of XeF2; here no oxidation is involved. krypton (Kr), chemical element, a rare gas of Group 18 (noble gases) of the periodic table, which forms relatively few chemical compounds.
