Xenon

Xenon is a chemical element wi the seembol Xe an atomic nummer 54. It is a colourless, hivy, odorless noble gas, that occurs in the Yird's atmosphere in trace amoonts. Altho generally unreactive, xenon can unnergo a few chemical reactions sic as the furmation o xenon hexafluoroplatinate, the first noble gas compound tae be synthesized. Xenon is uised in flash lamps an arc lamps, an as a general anesthetic. The first excimer laser design uised a xenon dimer molecule (Xe2) as the lasin medium, an the earliest laser designs uised xenon flash lamps as pumps. Xenon is uised tae sairch for hypothetical waikly interactin massive pairticles an as the propellant for ion thrusters in spacecraft. an for the three ion propulsion engines on NASA's Dawn Spacecraft. Naiturally occurrin xenon consists o aicht stable isotopes. Mair nor 40 unstable xenon isotopes unnergae radioactive decay, an the isotope ratios o xenon are an important tuil for studyin the early history o the Solar Seestem. Radioactive xenon-135 is produced bi beta decay frae iodine-135 (a product o nuclear fission), an is the maist signeeficant (an unwantit) neutron absorber in nuclear reactors.
