Buy Xenon (Xe) Cas 7440-63-3
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.[16] 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.[17][18][19]
Xenon is used in flash lamps[20] and arc lamps,[21] and as a general anesthetic.[22] The first excimer laser design used a xenon dimer molecule (Xe2) as the lasing medium,[23] and the earliest laser designs used xenon flash lamps as pumps.[24] Xenon is also used to search for hypothetical weakly interacting massive particles[25] and as a propellant for ion thrusters in spacecraft.

Naturally occurring xenon consists of seven stable isotopes and two long-lived radioactive isotopes. More than 40 unstable xenon isotopes undergo radioactive decay, and the isotope ratios of xenon are an important tool for studying the early history of the Solar System.[27] Radioactive xenon-135 is produced by beta decay from iodine-135 (a product of nuclear fission), and is the most significant (and unwanted) neutron absorber in nuclear reactors.[28]
History
Xenon was discovered in England by the Scottish chemist William Ramsay and English chemist Morris Travers on July 12, 1898,[29] shortly after their discovery of the elements krypton and neon. They found xenon in the residue left over from evaporating components of liquid air.[30][31] Ramsay suggested the name xenon for this gas from the Greek word ξένον xénon, neuter singular form of ξένος xénos, meaning ‘foreign(er)’, ‘strange(r)’, or ‘guest’.[32][33] In 1902, Ramsay estimated the proportion of xenon in the Earth’s atmosphere to be one part in 20 million.[34]
During the 1930s, American engineer Harold Edgerton began exploring strobe light technology for high speed photography. This led him to the invention of the xenon flash lamp in which light is generated by passing brief electric current through a tube filled with xenon gas. In 1934, Edgerton was able to generate flashes as brief as one microsecond with this method.[20][35][36]
In 1939, American physician Albert R. Behnke Jr. began exploring the causes of “drunkenness” in deep-sea divers. He tested the effects of varying the breathing mixtures on his subjects, and discovered that this caused the divers to perceive a change in depth. From his results, he deduced that xenon gas could serve as an anesthetic. Although Russian toxicologist Nikolay V. Lazarev apparently studied xenon anesthesia in 1941, the first published report confirming xenon anesthesia was in 1946 by American medical researcher John H. Lawrence, who experimented on mice. Xenon was first used as a surgical anesthetic in 1951 by American anesthesiologist Stuart C. Cullen, who successfully used it with two patients. Buy Xenon (Xe) Cas 7440-63-3
Xenon and the other noble gases were for a long time considered to be completely chemically inert and not able to form compounds. However, while teaching at the University of British Columbia, Neil Bartlett discovered that the gas platinum hexafluoride (PtF6) was a powerful oxidizing agent that could oxidize oxygen gas (O2) to form dioxygenyl hexafluoroplatinate (O+
2[PtF
6]−
).[38] Since O2 (1165 kJ/mol) and xenon (1170 kJ/mol) have almost the same first ionization potential, Bartlett realized that platinum hexafluoride might also be able to oxidize xenon. On March 23, 1962, he mixed the two gases and produced the first known compound of a noble gas, xenon hexafluoroplatinate.[39][19]
Bartlett thought its composition to be Xe+[PtF6]−, but later work revealed that it was probably a mixture of various xenon-containing salts.[40][41][42] Since then, many other xenon compounds have been discovered,[43] in addition to some compounds of the noble gases argon, krypton, and radon, including argon fluorohydride (HArF),[44] krypton difluoride (KrF2),[45][46] and radon fluoride.[47] By 1971, more than 80 xenon compounds were known.[48][49]
In November 1989, IBM scientists demonstrated a technology capable of manipulating individual atoms. The program, called IBM in atoms, used a scanning tunneling microscope to arrange 35 individual xenon atoms on a substrate of chilled crystal of nickel to spell out the three-letter company initialism. It was the first-time atoms had been precisely positioned on a flat surface.[50]
Characteristics
Xenon has atomic number 54; that is, its nucleus contains 54 protons. At standard temperature and pressure, pure xenon gas has a density of 5.894 kg/m3, about 4.5 times the density of the Earth’s atmosphere at sea level, 1.217 kg/m3.[51] As a liquid, xenon has a density of up to 3.100 g/mL, with the density maximum occurring at the triple point.[52] Liquid xenon has a high polarizability due to its large atomic volume, and thus is an excellent solvent. It can dissolve hydrocarbons, biological molecules, and even water.[53] Under the same conditions, the density of solid xenon, 3.640 g/cm3,[52] is greater than the average density of granite, 2.75 g/cm3. Under gigapascals of pressure, xenon forms a metallic phase.[54]
Solid xenon changes from Face-centered cubic (fcc) to hexagonal close packed (hcp) crystal phase under pressure and begins to turn metallic at about 140 GPa, with no noticeable volume change in the hcp phase.[55] It is completely metallic at 155 GPa.[56] When metallized, xenon appears sky blue because it absorbs red light and transmits other visible frequencies. Such behavior is unusual for a metal and is explained by the relatively small width of the electron bands in that state.

Liquid or solid xenon nanoparticles can be formed at room temperature by implanting Xe+ ions into a solid matrix. Many solids have lattice constants smaller than solid Xe. This results in compression of the implanted Xe to pressures that may be sufficient for its liquefaction or solidification. Buy Xenon (Xe) Cas 7440-63-3

The XENON project, operating at the Gran Sasso National Laboratory in Italy, utilizes large detectors filled with liquid xenon . These detectors aim to capture weakly interacting massive particles (WIMPs), which are a theorized candidate for dark matter. When a WIMP collides with a xenon nucleus, it produces minute amounts of light and ionization. These signals are then captured by the detector, and any excess events beyond known background noise could potentially indicate the presence of dark matter.
