All of the Noble Gasses * Helium * Neon * Argon * Krypton * Xenon * Radon
unreactive nonmetals are called noble gases
These elements are the noble gases: He, Ne, Ar, Kr, Xe, Rn.
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration. Hence they are chemically inert and generally do not form compounds under normal conditions.
They don't, under normal circumstances, react with other elements to form compounds.
Noble gases do not ionize under normal circumstances. Although they do under critical conditions with higher temperatures.
No. They are noble gases and will not react under normal conditions.
Well it of course depends on what you mean by 'normal conditions' but realistically, No. Under abnormal conditions all the nobel gases have been forced to react and make compounds with the exception of Helium and Neon.

Nickel Doesn't react with water under normal conditions
Platinum does not react with sulfuric acid under normal conditions.
Inert means non-reactive. Inert gases do not react with fluorine and oxygen except under exceptional conditions that do not occure naturally on the Earth.
because they obey octet rule and hence have stable electronic configuration (8 valence electrons)

Of the elemental gases and under normal conditions, hydrogen is explosive in the presence of air or oxygen. Under normal conditions there are a large number of inorganic and organic compounds that are explosive gases. Methane, CH4, is explosive in the same way hydrogen is, and so it ethane, propane, butane, .... Gases that are explosive in and of themselves are the various compounds of Nitrogen: NO NO2 N2O2
