•History

xenon (Xe), chemical element, a heavy and extremely rare gas of Group 18 (noble gases) of the periodic table. It was the first noble gas found to form true chemical compounds. More than 4.5 times heavier than air, xenon is colorless, odorless, and tasteless. Solid xenon belongs to the face-centered cubic crystal system, which implies that its molecules, which consist of single atoms, behave as spheres packed together as closely as possible. The name xenon...
