Xenon is a chemical element; it has symbol Xe and atomic number 54. It is a dense, colorless, odorless noble gas found in Earth's atmosphere in trace amounts. [17] . Although generally unreactive, it can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate, the first noble gas compound to be synthesized. [18][19][20]

2025年2月28日 · 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.

2020年5月22日 · Xenon is a rare gas in the Earth’s atmosphere, present at a concentration of about 1 part per 11.5 million (0.087 parts per million). Although it’s rare, the best source of the element is extraction from liquid air. Xenon also occurs in the Martian atmosphere at about the same concentration.

Xenon (Xe) - Xenon is a rare, colorless, odorless, and chemically unreactive gas with atomic number 54 and represented with the symbol Xe in the Periodic Table. Xenon was discovered by William Ramsay. Learn applications, properties and the atomic mass of xenon.

Xenon is a chemical element with symbol Xe and atomic number 54. Classified as a noble gas, Xenon is a gas at room temperature. [Kr]5s 2 4d 10 5p 6. B. Cordero, V. Gómez, A.E. Platero-Prats, M. Revés, J. Echeverría, E. Cremades, F. Barragán, S. Alvarez, Dalton Trans. 2008, 21, 2832-2838. DOI:10.1039/b801115j PMID:18478144. 1 S 0.

2024年9月26日 · Xenon may be one of the rarest gases on Earth, but it has some incredible uses, from bright lights to space travel. Even though you can’t see it or smell it, xenon is a powerful element with some surprising jobs in today’s world.

Xenon is an element with the symbol Xe, has an atomic number 54, and belongs to group 18 of the periodic table. Xe is a monoatomic, inert gas, first discovered in 1898 by British chemists William Ramsay (1852-1916) and Morris Travers (1872-1961) in the residue left after partial evaporation of liquid air (with krypton as an impurity).[1]

Xenon is used in search of hypothetical weakly interacting massive particles. Several satellites use xenon ion propulsion system to keep them in orbit and in some other space craft. Xenon is widely used in the preparation of 5-fluorouracil, a drug used to treat certain cancer.
