  2. 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 ...

  4. Noble gas - Wikipedia

    en.wikipedia.org/wiki/Noble_gas

    An endohedral fullerene compound containing a noble gas atom. Noble gases can form endohedral fullerene compounds, in which the noble gas atom is trapped inside a fullerene molecule. In 1993, it was discovered that when C 60, a spherical molecule consisting of 60 carbon atoms, is exposed to noble gases at high pressure, complexes such as He@C

  5. Neil Bartlett (chemist) - Wikipedia

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

    In 1973, he was made a Fellow of the Royal Society (United Kingdom). In 1976 he received the Welch Award in Chemistry for his synthesis of chemical compounds of noble gases and the consequent opening of broad new fields of research in the inorganic chemistry. He was elected a Fellow of the American Academy of Arts and Sciences in 1977. [10]

  6. Helium compounds - Wikipedia

    en.wikipedia.org/wiki/Helium_compounds

    Helium is the smallest and the lightest noble gas and one of the most unreactive elements, so it was commonly considered that helium compounds cannot exist at all, or at least under normal conditions. [1] Helium's first ionization energy of 24.57 eV is the highest of any element. [2]

  7. Chemically inert - Wikipedia

    en.wikipedia.org/wiki/Chemically_inert

    They are said to acquire a noble gas configuration, or a full electron configuration. It is now known that most of these gases in fact do react to form chemical compounds, such as xenon tetrafluoride. Hence, they have been renamed to 'noble gases', as the only two of these we know truly to be inert are helium and neon.

  9. Radon compounds - Wikipedia

    en.wikipedia.org/wiki/Radon_compounds

    Radon compounds are chemical compounds formed by the element radon (Rn). Radon is a noble gas, i.e. a zero-valence element, and is chemically not very reactive. The 3.8-day half-life of radon-222 makes it useful in physical sciences as a natural tracer. Because radon is a gas under normal circumstances, and its decay-chain parents are not, it ...
