Why Xeon Doesnt React :: essays research papers

Xenon is a rare, colorless, odorless, tasteless, chemically unreactive gas. It is one of the inert gas elements found in collection 0 of the periodic table. Xenon was long considered incapable of chemical reaction, just in 1962 Neil Bartlett, a Canadian chemist, reported synthesis of atomic number 54 hexafluoroplatinate, XePtF6, a true compound. Before 1962, people thought that xenon and other dire gases were unable to form compounds. Now, xenons reported compounds are sodium perxenate, xenon deutetrate, xenon hydrate, difluoride, tetrafluride and hexafluoride. Xenon is present in the atmosphere in extremely depressive disorder concentration (about one part in 20 million). It is obtained commercially from watery air. Xenon is used in certain photographic flash lamps, in high-intensity arc lamps for motion picture projection, and in high-pressure arc lamps to earn ultraviolet light. It is used in numerous instruments for radiation detection, e.g., neutron and X-ray counters an d blether chambers. It has found some use in medicine, e.g., as an experimental anesthetic. by nature occurring xenon is a mixture of 9 stable isotopes 20 impermanent radioactive isotopes are also known. A mixture of stable and dubious isotopes of xenon is produced in nuclear reactors during neutron fission of uranium one of these, xenon-135, is a very good neutron absorber and must be removed since it poisons the reaction. Xenon was sight spectroscopically in 1898 by William Ramsay and M. W. Travers, who obtained it by fractional distillation of an impure have of krypton. Xenon as well as the other noble gasses quest an incredible amount of pressure for them to react, which makes them very inert since such a large amount of pressure does not occur naturally.
