  • Isotopes of xenon — Naturally occurring xenon (Xe) is made of nine stable isotopes. (124Xe, 134Xe and 136Xe are predicted to undergo double beta decay, but this has never been observed, so they are considered to be stable.) [… …   Wikipedia

  • List of fictional elements, materials, isotopes and atomic particles — This list contains chemical elements, materials, isotopes or (sub)atomic particle that exist primarily in works of fiction (usually fantasy or science fiction).
