    en.wikipedia.org/wiki/Combustibility_and...

    A non-combustible material [17] is a substance that does not ignite, burn, support combustion, or release flammable vapors when subject to fire or heat, in the form in which it is used and under conditions anticipated. Any solid substance complying with either of two sets of passing criteria listed in Section 8 of ASTM E 136 when the substance ...

  3. 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.

  4. Helium compounds - Wikipedia

    en.wikipedia.org/wiki/Helium_compounds

    Helium has the highest ionisation energy, so a He + ion will strip electrons off any other neutral atom or molecule. However it can also then bind to the ion produced. The He + ion can be studied in gas, or in liquid helium. Its chemistry is not completely trivial. For example, He + can react with SF 6 to yield SF + 6 or SF + 5 and atomic ...

    The Rollin film also covers the interior of the larger container; if it were not sealed, the helium II would creep out and escape. [30] Helium II is a superfluid, a quantum mechanical state of matter with strange properties. For example, when it flows through capillaries as thin as 10 to 100 nm it has no measurable viscosity.

  8. Noble gas - Wikipedia

    en.wikipedia.org/wiki/Noble_gas

    The inertness of noble gases makes them useful whenever chemical reactions are unwanted. For example, argon is used as a shielding gas in welding and as a filler gas in incandescent light bulbs. Helium is used to provide buoyancy in blimps and balloons. Helium and neon are also used as refrigerants due to their low boiling points.
