More essentials: ~group number: 18 ~period number: 5 ~Block: p-block ~standard state: gas at 298 K ~classification: Non-metallic ~xenon is a "noble" or "inert" gas present in the atmosphere to a small extent ~It can be highly explosive xenon trioxide ~*Metallic xenon is produced by applying several hundred kilobars of pressure. Xenon in a vacuum tube produces a blue glow when excited by an electrical discharge and finds use in strobe lamps. It is an odorless, colorless, inert gas.*~ |
Isolation of xenon: Xenon is present to a small extent in the atmosphere (less than one ppm by volume) and is obtained as a byproduct fromt he liquefaction and separation of air. This would not normally be carried out in the laboratory and xenon is available commercially in cylinders in high pressure. |
