Xenon has been used as a general anesthetic, but it is more expensive than conventional anesthetics. [154] Xenon interacts with many different receptors and ion channels, and like many theoretically multi-modal inhalation anesthetics, these interactions are likely complementary. Xenon is a high-affinity glycine-site NMDA receptor antagonist. [155]
Xenon-136 is an isotope of xenon that undergoes double beta decay to barium-136 with a very long half-life of 2.11 × 10 21 years, more than 10 orders of magnitude longer than the age of the universe ((13.799 ± 0.021) × 10 9 years). It is being used in the Enriched Xenon Observatory experiment to search for neutrinoless double beta decay.
An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion. An ion thruster creates a cloud of positive ions from a neutral gas by ionizing it to extract some electrons from its atoms. The ions are then accelerated using electricity to create thrust.
Xenon ions are synthesized directly in the discharge or through successive reactions that involve Rg +, Rg 2+ as well as other ionic or excited species. Figure 1 gives an example where Rg=Ne and figure 6 where Rg=He. [116] [119] [142] [130] [143] [144] The Cl − ions are basically formed by dissociative attachment from an HCl electron: [32]
Recently, [when?] xenon has been shown to produce a wide variety of compounds of the type XeO n X 2 where n is 1, 2 or 3 and X is any electronegative group, such as CF 3, C(SO 2 CF 3) 3, N(SO 2 F) 2, N(SO 2 CF 3) 2, OTeF 5, O(IO 2 F 2), etc.; the range of compounds is impressive, similar to that seen with the neighbouring element iodine ...
Compared with solar xenon, Earth's atmospheric Xe is enriched in heavy isotopes by 3 to 4% per atomic mass unit (amu). [18] However, the total abundance of xenon gas is depleted by one order of magnitude relative to other noble gases. [15] The elemental depletion while relative enrichment in heavy isotopes is called the "Xenon paradox".
The xenonium ion, XeH +, is an onium compound, consisting of protonated xenon. Although the existence of the xenonium salts has not been proven, the isolated XeH + ion is known. [2] Salts of the fluoroxenonium ion, XeF +, are known to exist, for instance fluoroxenonium pentafluoroplatinate (XeFPtF 5), more commonly known as xenon ...
Xenon difluoride is a strong fluorinating and oxidizing agent. [26] [27] With fluoride ion acceptors, it forms XeF + and Xe 2 F + 3 species which are even more powerful fluorinators. [1] Among the fluorination reactions that xenon difluoride undergoes are: Oxidative fluorination: Ph 3 TeF + XeF 2 → Ph 3 TeF 3 + Xe. Reductive fluorination:
