- Xenon (atomic number 54, symbol Xe) is a gas and chemical element that was first isolated in 1898 by the English chemist Morris Travers and the Scottish chemist William Ramsay. Ramsey also discovered the elements krypton and neon. Properties and Isotopes This is a noble gas which is tasteless, colorless, and odorless. It is a nonmetal and gas at room temperature. It forms compounds such as xenon hexafluoroplatinate and dioxygenyl hexafluoroplatinate. Over 80 xenon compounds have been studied.

Xenon Xenon is a chemical element with symbol Xe and atomic number 54. It is a colorless, dense, odorless noble gas, that occurs in the Earth's atmosphere in trace amounts. Although generally unreactive, xenon can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate, the first noble gas compound to be synthesized.

Facts About Xenon Xenon was discovered in July 1898 by William Ramsay and Morris Travers at University College London. They had already extracted neon, argon, and krypton from liquid air, and wondered if it contained other gases.

Xenon: isotope data Xenon: isotope data. Of the nine stable Xenon isotopes, several are used in various medical and scientific applications. Xe-124 is used in the production of two radioisotopes: I-123 and I-125. I-123 is used extensively in diagnostic procedures while I-125 is used in the treatment of prostate cancer.

- Xenon-129, a stable isotope that makes up about a quarter of naturally occurring xenon, turns out to be ideal for use in magnetic resonance imaging. Usually these instruments only detect hydrogen nuclei in water and fats - ideal for most tissue, but are of no use when looking at air spaces such as the lungs.

Arsenic The special characteristics of xenon-it exists naturally in nine different isotopes, ranging in atomic mass from 124 (with 70 neutrons per atom) to 136 (with 82 neutrons per atom) - allows us to learn more about the process by which the layers of atmosphere were stripped off Mars than using measurements of other gases.

Xenon tetroxide All eight valence electrons of xenon are involved in the bonds with the oxygen, and the oxidation state of the xenon atom is +8. Oxygen is the only element that can bring xenon up to its highest oxidation state; even fluorine can only give XeF6 (+6). Two other short-lived xenon compounds with an oxidation state of +8, XeO 3 F 2 and XeO 2 F 4, are accessible by the reaction of xenon tetroxide with xenon hexafluoride.

p -Xylene p-Xylene is an aromatic hydrocarbon. It is one of the three isomers of dimethylbenzene known collectively as xylenes. The p- stands for para-, indicating that the two methyl groups in p-xylene occupy the diametrically opposite substituent positions 1 and 4. It is in the positions of the two methyl groups, their arene substitution pattern, that it differs from the other isomers, o-xylene and m-xylene. All have the same chemical formula C6H4(CH3)2. All xylene isomers are colorless and highly flamm

XENON Xenon is a colorless, odorless gas. It has a boiling point of -108.13°C (-162.5°F) and a melting point of C. It may seem strange to talk about the melting point and boiling point of a gas. So think about the opposite of those two terms.

- Xenon lamps are also used in ruby lasers. Xenon ion propulsion systems are used by several satellites to keep them in orbit, and in some other spacecraft. Xenon difluoride is used to etch silicon microprocessors. It is also used in the manufacture of 5-fluorouracil, a drug used to treat certain types of cancer.

Xenon: the essentials xenon is a noble or inert gas present in the atmosphere to a small extent. Xenon is present in the Martian atmosphere to the extent of about 0.08 ppm. Before 1962, it was …generally assumed that xenon and other noble gases were unable to form compounds.

Neon Neon is a chemical element with symbol Ne and atomic number 10 and is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. It was discovered (along with krypton and xenon) in 1898 as one of the three residual rare inert elements remaining in dry air, after nitrogen, oxygen, argon and carbon dioxide were removed.

- An isotope of xenon has an atomic number of 54 and contains 77 neutrons. The atomic number of an element is the number of protons in its nucleus. Always. The mass number of an atom is the number of protons plus the number of neutrons in it. And tha … t means an isotope of element 54 (xenon) that has 77 neutrons in its nucleus has a mass number of 54 + 77 or 131, and you'll have an atom of 131Xe.

Xylene Xylene (from Greek ξύλο, xylo, wood), xylol or dimethylbenzene is any one of three isomers of dimethylbenzene, or a combination thereof. With the formula (CH3)2C6H4, each of the three compounds has a central benzene ring with two methyl groups attached at substituents. They are all colorless, flammable liquids, some of which are of great industrial value. The mixture is referred to as both xylene and, more precisely, xylenes.
