Hey here's your answer

They are called the noble gases because they are very unreactive. The highest occupied energy levels (outermost shells) of their atoms are full: helium atoms have two electrons in their outer energy level.

Hope this answer helps

Because they are nobel gases and their last shell is fully completed . that's why the are non reactive gases.
