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

4
A Noble Gas
  • Its 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.

5
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.

6
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.

7
Physical Properties
  • Density 5.894 g/L
  • Melting Point 161.4K
  • Boiling Point 165.03K
  • Heat Capacity 20.786 JmolK

8
Other Characteristics
  • Protons 54
  • Neutrons 54
  • Electrons 54
  • Non Metal

9
Appearance
  • Xenon is colorless

10
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.

11
Occurrence of Xenon
  • Trace gas in Earths 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 Suns atmosphere, on
    Earth, and in asteroids and comets.
  • Mars shows a higher proportion than the Earth or
    the Sun.

12
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.

13
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.

14
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.
