Question

why noble gases are inert at room temperature​

Answer 1

Answer:

All of the noble gases have full outer shells with eight electrons. ... The fact that their outer shells are full means they are quite happy and don't need to react with other elements. In fact, they rarely combine with other elements. That non-reactivity is why they are called inert.
