Transcript of Science Element Project

My Element is....... Xenon!!! Xenon Xe Symbol: Full Name Atomic Number: 54 Atomic Mass: 131.29 amu # Of Protons: 54 # Of Neutrons: 77 # Of Electrons: 54 Melting Point: -111.9 °C Boiling Point: State Of Matter: Gas Color: Colorless Gas Density: Sources 1.http://www.chemicalelements.com/elements/xe.html



5.http://www.chemicool.com/elements/xenon.html Origin: Xenon comes from the Greek word-Xenon, meaning stranger, and from the Greek word-Xenos, meaning strange Discovered by: Sir William Ramsay and Morris Travers in England in 1898 Interesting Facts!!!! Xenon produces a blue glow in a vacuum tube when excited by an electrical discharge[used in strobe lights].
Xenon is a byproduct formed when liquefying air.
Xenon is not normally kept in a laboratory
Xenon is the most dense of all the noble gases and the most expensive
A new use of Xenon could be in laser toys
The earth's atmosphere is about 0.0000087% xenon,or point 87 million percent xenon .005887 grams per cubic centimeter -108.1 °C Properties: Xenon is a noble gas.Xenon it's self is not toxic, its compounds are highly toxic due to their strong oxidizing characteristics. Some xenon compounds are colored. Metallic xenon has been produced. Excited xenon in a vacuum tube glows blue. Xenon is one of the heaviest gases; one liter of xenon weighs 5.842 grams. Sources: Xenon is found in the atmosphere at levels of approximately one part in twenty million. It is commercially obtained by extraction from liquid air. Xenon-133 and xenon-135 are produced by neutron irradiation in air cooled nuclear reactors. Uses Of Xenon 1. Lighting of all types, including strobe lights 2.Movie projection 3.Nuclear Reactor 4.Oxidizing Agents 5.Applications where a high molecular weight gas is needed. 6.Lamps used to excite ruby lasers. Cost, pure: $120 per 100g
