Brief description |
| |
Xenon is a noble or inert gas. However, xenon and other zero valance elements do form compounds. Although xenon is not toxic, its compounds are highly toxic due to their strong oxidizing characteristics. Some xenon compounds are colored. Metallic xenon has been produced. Excited xenon in a vacuum tube glows blue. Xenon is one of the heaviest gases; one liter of xenon weighs 5.842 grams.

Uses of Xenon |
| |
Xenon gas is used in electron tubes, bactericidal lamps, stobe lamps, and lamps used to excite ruby lasers. Xenon is used in applications where a high molecular weight gas is needed. The perxenates are used in analytical chemistry as oxidizing agents. Xenon-133 is useful as a radioisotope.
