Chemistry: An overview of the Periodic Table - The Noble Gases, helium, neon, argon, krypton, xenon and radon, videos for each noble gas
The meaning of NOBLE GAS is any of a group of rare gases that include helium, neon, argon, krypton, xenon, and usually radon and that exhibit great stability and extremely low reaction rates —called also inert gas.
Neon, argon, krypton, and xenon are obtained from air using the methods of liquefaction of gases, to convert elements to a liquid state, and fractional distillation, to separate mixtures into component parts. Helium is typically produced by separating it from natural gas, and radon is isolated ...
krypton and xenon compoundsRaman SpectroscopyX-ray crystallographyThe coordination chemistry of KrF2 has been limited, in contrast with that of XeF2, which exhibits a far richer coordination chemistry with mainゞroup and transition﹎etal cations. In the present work, reactions of [XeF5][AsF6] ...
For Ar, the gases measured in the re-extractions (Q-like composition) were added to the gas amounts in the main extraction step, if the former exceeded the uncertainty and ~3 % of the Ar amount in the main step (marked with * in Table 3). Table 3. Argon and Kr concentrations and...

Deep within the Precambrian basement rocks of the Earth, groundwaters can sustain subsurface microbial communities, and are targets of investigation both for geologic storage of carbon and/or nuclear waste, and for new reservoirs of rapidly depleting res
(Table2; Fig.7). In order to compare the noble gas to water ratio of the primitive Earth as formed by mixtures of comets and chondrites with that of the present day ESR, we need to now estimate how planetary processes would have affected the noble gas to water ratio of the ESR over...
