All contain a full outer shell of electrons
noble gases are also called inert gases due to their lack of reactivity
The most characteristic property of noble gases is their inertness or lack of reactivity due to having a full outer electron shell. This makes them stable and unreactive under normal conditions.
helium
Noble gases have completely filled orbitals. They are stable and chemically inert (non-reactive). So generally they will not accept / gain / share electrons and they do not form compounds.
No, they are the least reactive gasses.
Gases with eight valence electrons.
Because fluorine is having the most electronegativity and is the most reactive non metal.
Noble gases have completely filled outer most shell. They are chemically inert and exist as monoatomic species.
Helium is the most abundant of the Noble gases in the universe.
the noble gases
None of them.
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
