Noble gases are generally unreactive, butXENON compoundsare reactive. It is so because the electrons in Xe are much less strongly bound to the atom , owning to it's large size. Is the most reactive noble gas? Xe. Why are the noble gases found unbonded to other elements and by themselves...
- While noble gases are generally inert, some of them, such as xenon, krypton, and radon, can form compounds under specific conditions, particularly with highly electronegative elements like fluorine and oxygen. Therefore, this statement is not true. Hint: Think about exceptions in chemistry; ...
Hard constraints on the diffusion rate of noble gases in minerals and melts are therefore needed to estimate the losses of gases over geological time. Although most of the work to estimate material diffusivity is focused on minerals enriched in radioactive elements, it is essential to obtain the...
“Class 2.1 - Flammable Gas can be defined asgases at 20 °C and a standard temperature of 101.3 kPa are ignitable when in a mixture of 13% or less by volume in air.” Examples of flammable gases regularly used in workplaces include: LPG, acetylene, hydrogen, propane, propylene and meth...
noble gases are generally inert as they all usually have the noble gas configuration (exception is helium) which I think means that all the shells of electrons are full thus there is no need generally for a noble gas to bond with another atom in order to become more stable and/or lose ...
(Xe 131) is subject to quadrupolar electric interaction causing it to be sensitive to electrical field gradients, and thus adds an extra term to one precession frequency violating the assumption that the noble gases are generally insensitive to environmental conditions other than magnetic field. The ...

noble gases, with the lightest displaying the greatest depletions. This pattern seems consistent with preferential retention of the generally more reactive heavier noble gases, and was likely established during trapping into solid grains. The Ne/Ar ratios of the terrestrial planets and chondrites are ...
Two hypothesis have been discussed: (1) a deep argon-like-air source, due to subduction of air-rich sediments and/or (2) a preferential loss of Ar, in comparison to lighter noble gases, from silicic melts. Helium isotopic analysis of gas samples recently collected from crater and submarine...
