Noble Gas Chemical Compounds

Noble Gas Chemical Compounds The noble gases do form chemical compounds, even though they have filled electron valence shells. Here is a look at how they form compounds and some examples. How Noble Gases Form Compounds Helium, neon, argon, krypton, xenon, radon have completed valence electron shells, so they are highly stable. However, the filled inner electron shells tend to provide a sort of electrical shielding, making it possible to ionize the outer electrons. Under ordinary conditions, noble gases are inert and dont form compounds, but when ionized or under pressure, they will sometimes working into the matrix of another molecule or combine with highly reactive ions. Reaction with halogens is most favorable, where the noble gas loses an electron and acts as a positively charged ion to form a compound. Examples of Noble Gas Compounds Many types of noble gas compounds are theoretically possible. This list includes compounds which have been observed. noble gas halides (e.g., xenon hexafluoride - XeF6, krypton fluoride - KrF2)noble gas clathrates and clathrate hydrates (e.g., Ar, Kr, and Xe clathrates with ÃŽ ²-quinol, 133Xe clathrate)noble gas coordination compoundsnoble gas hydrates (e.g., Xe ·6H2O)helium hydride ion - HeHoxyfluorides (e.g., XeOF2, XeOF4, XeO2F2, XeO3F2, XeO2F4)HArFxenon hexafluoroplatinate (XeFPtF6 and XeFPt2F11)fullerene compounds (e.g., HeC60 and NeC60) Uses of Noble Gas Compounds Presently most noble gas compounds are used to help store noble gases at high density or as potent oxidizers. The oxidizers are useful for applications where it is important to avoid introducing impurities into a reaction. When the compound participates in a reaction, the inert noble gas is released.
