Historia
Xenon was discovered in England by the Scottish chemist William Ramsay and English chemist Morris Travers in 1898.
They found xenon in the residue left over from evaporating components of liquid air.
Spectroscopic analysis showed the previously unseen beautiful blue lines that indicated the presence of a new element.

Käyttö
Xenon is used in flash lamps and arc lamps, and in photographic flashes.
Xenon is used in medicine as a general anesthetic and in medical imaging.
In nuclear energy applications, xenon is used in bubble chambers, probes, and in other areas where a high molecular weight and inert nature is desirable.
