Question

why are noble gases less reactive? ​

Answer 1

Hello friend....

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.

Hope it helped u...☺️☺️

Answer 2

Because their octate and duplate are complete so they neither donate electron nor gain electron.

That's why they are less reactive.
