Although the second most abundant element in the cosmos is helium, noble gases are also called rare gases. The reason is that they are not abundant on terrestrial planets like the Earth, which is characterized by orders of magnitude depletion of—particularly light—noble gases when compared to the cosmic element abundance pattern.

THE PERIODIC TABLE OF THE Elements, as set out by Dmitry Mendeleyev or Lother Meyer, had not allowed for the discovery of a group of elements between the highly electronegative halogens and the electropositive alkalis. So the discovery of the unreactive monatomic gas argon by Lord Rayleigh and William Ramsay in 1895 came as a total surprise.

Abstract This paper presents experimental data for the trapped noble gas contents in a variety of shales and related samples. These data, along with those previously available, indicate that the normal sedimentary rock pattern is one of progressive enrichment of the heavier gases in comparison with the proportions in air, from which sedimentary rock ...

Noble gas studies have been done on well-documented samples from two very different solar system bodies, the Earth and Moon. There is one other planet, Mars, from which we have samples, but those samples are nearly 20 (at the start of 2002) Martian meteorites, rocks from unknown locales on Mars.

Excluding 3He, the rare-gas nuclei amenable to NMR investigation are 21Ne, 83Kr, 129Xe, and 131Xe. Of these only Kr and Xe form compounds that are stable under ordinary conditions, and only 129Xe NMR spectra have been observed in chemical environments other than the pure element, although Kr compounds have been characterized by 19F NMR spectroscopy.(1)

Xenon and krypton are noble gases of group O. They are chemically inert at body temperature with limited solubility in aqueous media. The physical half-lives, decay mode and gamma energies of 127/133Xe and 81mKr are listed in Table 13.1.

A large fraction of gases dissolved in surface and groundwater, mainly N2, O2 and the noble gases He, Ne, Ar, Kr and Xe, originate from the atmosphere. Whenever water comes into contact with the atmosphere, or other phases such as natural gas, oil and solid organic matter, gases are exchanged and gas concentrations of the individual phases record some ...
