The elements of which group are nonreactive? halogens alkaline earth metals noble gases alkali metals

noble gases

Explanation: The elements whose valence shell is already filled is stable and thus don not lose or gain electron and thus do not react.

Halogen is the name given to fluorine family which have 5 valence electrons and thus easily gain electrons to attain stable configuration.

Alkaline earth metal is the name given to group 2 elements which have 2 valence electrons and thus easily lose 2 electrons to attain stable configuration.

Noble gases is the name given to group 18 elements which have 8 valence electrons and thus do not lose or gain electrons and thus is non reactive.

Alkali metals is the name given to group 1 elements which have 1 valence electrons and thus easily lose 1 electron to attain stable configuration.

i wish i could but this one is weird give me abc and i can solve it.
