  2. Neil Bartlett (chemist) - Wikipedia

    en.wikipedia.org/wiki/Neil_Bartlett_(chemist)

    Neil Bartlett was born on 15 September 1932 in Newcastle-upon-Tyne, England. [1] Bartlett's interest in chemistry dated back to an experiment at Heaton Grammar School when he was only eleven years old, in which he prepared "beautiful, well-formed" crystals by reaction of aqueous ammonia with copper sulfate.

  3. Noble gas - Wikipedia

    en.wikipedia.org/wiki/Noble_gas

    The noble gases have also been referred to as inert gases, but this label is deprecated as many noble gas compounds are now known. [6] Rare gases is another term that was used, [ 7 ] but this is also inaccurate because argon forms a fairly considerable part (0.94% by volume, 1.3% by mass) of the Earth's atmosphere due to decay of radioactive ...

  4. Xenon hexafluoroplatinate - Wikipedia

    en.wikipedia.org/wiki/Xenon_hexafluoroplatinate

    Xenon hexafluoroplatinate is the product of the reaction of platinum hexafluoride with xenon, in an experiment that proved the chemical reactivity of the noble gases.This experiment was performed by Neil Bartlett at the University of British Columbia, who formulated the product as "Xe + [PtF 6] −", although subsequent work suggests that Bartlett's product was probably a salt mixture and did ...

  5. Noble gas compound - Wikipedia

    en.wikipedia.org/wiki/Noble_gas_compound

    Structure of a noble-gas atom caged within a buckminsterfullerene (C 60) molecule. Noble gases can also form endohedral fullerene compounds where the noble gas atom is trapped inside a fullerene molecule. In 1993, it was discovered that when C 60 is exposed to a pressure of around 3 bar of He or Ne, the complexes He@C 60 and Ne@C 60 are formed ...

  6. Isotope-ratio mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Isotope-ratio_mass...

    Samples must be introduced to the mass spectrometer as pure gases, achieved through combustion, gas chromatographic feeds, [6] or chemical trapping. By comparing the detected isotopic ratios to a measured standard, an accurate determination of the isotopic make up of the sample is obtained. For example, carbon isotope ratios are measured ...

  8. Matrix isolation - Wikipedia

    en.wikipedia.org/wiki/Matrix_isolation

    For example, the solid noble gas krypton can be used to form an inert matrix within which a reactive F 3 − ion can sit in chemical isolation. [1] The reactive species can either be generated outside (before deposition) the apparatus and then be condensed, inside the matrix (after deposition) by irradiating or heating a precursor, or by ...

  9. Chemically inert - Wikipedia

    en.wikipedia.org/wiki/Chemically_inert

    The noble gases (helium, neon, argon, krypton, xenon and radon) were previously known as 'inert gases' because of their perceived lack of participation in any chemical reactions. The reason for this is that their outermost electron shells (valence shells) are completely filled, so that they have little tendency to gain or lose electrons.
