Krypton and Xenon – About Elements

Krypton

Krypton is a member of group 18 (noble gases) elements. A colorless, odorless, tasteless noble gas, krypton occurs in trace amounts in the atmosphere and is often used with other rare gases in fluorescent lamps.

Xenon

Xenon is a colorless, dense, odorless noble gas found in the Earth’s atmosphere in trace amounts.[10] Although generally unreactive, xenon can undergo a few chemical reactions. Xenon was first discovered in 1898 by the Scottish chemist William Ramsay and English chemist Morris Travers. The name xenon for this gas comes from the Greek word ξένον [xenon], neuter singular form of ξένος [xenos], meaning ‘foreign(er)’, ‘strange(r)’, or ‘guest’. In nuclear industry, especially artificial xenon 135 has a tremendous impact on the operation of a nuclear reactor. For physicists and for reactor operators, it is important to understand the mechanisms that produce and remove xenon from the reactor to predict how the reactor will respond following changes in power level.

Krypton and Xenon – Applications

Krypton

Krypton’s multiple emission lines make ionized krypton gas discharges appear whitish, which in turn makes krypton-based bulbs useful in photography as a white light source. Krypton is used in some photographic flashes for high speed photography. Krypton is also used in MRI/CT techniques.

Xenon

Xenon is useful in the following applications. The white flash of light produced by xenon makes it suitable for usage in strobe lights and to power ruby lasers. Xenon is used in light-emitting devices called xenon flash lamps, used in photographic flashes and stroboscopic lamps.
