Get it Now Xenon Atomic Number: 54 One of the Noble Gases Every element wants to be like it! Atomic Weight: 131.293g Exists as a gas in the environment

A Noble Gas It’s outer shell is full of electrons Making it a stable element. Not wanting to give away or gain an electron. It just wants to be who it is.

A Noble Gas Xenon and other noble gases had for a long time been considered to be completely chemically inert and not able to form compounds. In 1962 at the University of British Columbia, the first xenon compound, xenon hexafluoroplatinate, was synthesized by Neil Bartlett.

Characteristics In a gas filled tube, xenon emits a blue glow when the gas is excited by electrical discharge. Xenon emits a band of emission lines that span the visual spectrum, but the most intense lines occur in the region of blue light, which produces the coloration.

Physical Properties Density: 5.894 g/L Melting Point: 161.4K Boiling Point: 165.03K Heat Capacity: 20.786 J*mol*K

Other Characteristics Protons: 54 Neutrons: 54 Electrons: 54 Non Metal

Appearance Xenon is colorless

History Discovered in England by William Ramsay and Morris Travers on July 12, 1898. Found in the residue left over from evaporating components of liquid air. Named derived from the Greek word xenon, meaning foreign, strange or host.

Occurrence of Xenon Trace gas in Earth’s atmosphere, occurring at 0.087 parts per million. Also found in gases emitted from some mineral springs. Radioactive species of xenon are produced by neutron irradiation of fissionable material within nuclear reactors. Obtained commercially as a byproduct of the separation of air into oxygen and nitrogen. Relatively rare in the Sun’s atmosphere, on Earth, and in asteroids and comets. Mars shows a higher proportion than the Earth or the Sun.

Uses Xenon Flash Lamp In 1934, Harold Edgerton while exploring strobe light technology for high speed photography, pushed the time resolution down to a millionth of a second by creating an electrical spark inside a gas tube filled with xenon gas.

Xenon Flash Lamps Used in photographic flashes and stroboscopic lamps to excite the active medium in lasers which then generates coherent light, to produce laser power for inertial confinement fusion.

Uses In 1939, Albert R. Behnke Jr. tested the effects of varying breathing mixtures on deep-sea divers. He deduced that xenon gas could serve as an anesthetic. Experiments employing xenon as an anesthetic on a human were first made in Russia by Lahzarev in 1941. Xenon was first used as a surgical anesthetic in 1951 by Stuart C. Cullen, who successfully operated on two patients.
