The stability of the noble gases is due to the fact that they?
have no electron in their outermost shells
have duplet or octet electron configurations
belong to group zero of the periodic table
are volatile in nature
Explanation
Noble / Rare gases belong to group 0 because they have no bonding electrons in their outermost shell to satisfy the octet rule for stability.
