Xenon (its name derived from the Greek word xenos, meaning "strange"), is the heaviest of the noble gases . Discovered in 1898 in London by Sir William Ramsay and Morris Travers while engaged in their investigations of liquid air, xenon accounts for less than 1 ppm of the volume of Earth's atmosphere. It is present in the Sun and in the atmospheres of Mars, Venus, and Mercury.

At room temperature xenon is a colorless, odorless gas. Upon freezing it forms a crystal with a face-centered cubic structure. The chief application of xenon gas is its use in various kinds of lamps. In an electric discharge

tube it produces a blue glow. Liquid xenon is used in some particle detectors that are used in space-based research.

Unlike the lighter noble gases, xenon is not produced by nucleosynthesis within stars. It is made during supernova explosions. It is also formed on Earth through radioactive decay (e.g., of iodine-135) and in fission reactions, and it is sometimes found in gases emitted from mineral springs. It has nine stable isotopes , of which xenon-129 and xenon-132 are the most abundant (26.4% and 26.9%, respectively).

Also, unlike the lighter noble gases, which are inert, xenon is able to form compounds, mostly with oxygen and fluorine.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
