The noble gas of…. Basic Facts and Knowledge of Xenon Xe or xenon isn’t a metal but rather is a gas specifically a noble gas with the…. atomic number of 54 atomic weight of 131.29 g.mol atomic volume of 42.9 atomic radius of 218 pm melting point of 161.3 K boiling point of 166.1 K Discovery Facts Xenon was discovered by Sir William Ramsay and M.W. Travers in 1898 in England. They discovered it after evaporating liquid air in the residue. Sir William Ramsay also discovered argon, helium, neon, and krypton. Hazardous Effects Xenon is a haphazard to peoples health. If ever inhaled it can cause people to feel dizzy, nausea, vomiting, passing out or even die. Xenon also is very hazardous to the environment. If it ever touches anything it will freeze it on contact due to the cold temperature of it. Uses Xenon can be used for multiple uses but mainly if you need an element or substance with a high molecular weight. It is mainly used for electron tubes, different types of lamps such as flash lamps, stroboscopic lamps and some more basic. Interesting Facts Xenon in Greek actually means “stranger” It is even possible to create metallic xenon. It is found in the atmosphere the ratio is 1:20,000,000 Summary Xenon is a noble gas. It is colorless, odorless, heavy, non metal. It can turn a bluish color when it is “excited” by and electric discharge. It can be found in the atmosphere even though it was discovered in in residue from evaporated liquid air. Can be very dangerous to health and is used where high molecular weight is needed. Extra Information : Noble Gases Can also be called inert gases Group VIII or Group O on the periodic table Helium, neon, argon, krypton, xenon, radon, ununoctium are all noble gases Have full valence shell Have high ionization energies Have negligible electronegative Low boiling point Bibliography Helmenstine, Anne Marie. “Xenon Facts.” About.com. 21st April 2010 <http://chemistry.about.com/od/elementfacts/a/xenon. htm>.
