Fun Facts

Xenon is the most dense of all the noble gases and the most expensive.



it is found at only 0.087 parts per million in Earth's atmosphere and 0.08 parts per million in Mar's atmosphere.


Jupiter has an exceptionally high amount of xenon, almost three times that of the Sun.


it can be used as a gas for ion engines.

Uses for Xenon

History of Xenon

Xenon was discovered in 1898 by Scottish chemist and physicist Sir William Ramsay (1852-1916) and English chemist Morris William Travers (1872-1961). Ramsay and Travers used liquid air to make their discovery. If air is cooled to a very low temperature, it changes from a gas to a liquid. As it warms up, it changes back to a gas. But this change does not take place all at once. As liquid air warms, one gas (nitrogen) boils away first. As the temperature increases further, another gas ( argon ) boils off. Still later, a third gas (oxygen) boils off. The first three gases to boil away (nitrogen, oxygen, and argon) make up 99.95 percent of air. It may look as if all the air is gone after the oxygen boils away, but it isn't. After the oxygen is gone, a tiny bit of liquid air remains. That liquid air contains other atmospheric gases. One of those gases is xenon. Ramsay and Travers first recognized the presence of xenon in liquid air on July 12, 1898. They named the element xenon for the Greek word that means "stranger."
