Nitrogen gas is more stable and it is an inert gas that's why it cannot react with a filament of the bulb. But if a bulb uses so long time. Nitrogen gets emission gradually. That's why the electric bulb will deemed.

It is Argon, not Nitrogen. It might be Nitrogen, but the best answer is Argon. Argon is an Inert Gas, it does NOT react to other elements. Nitrogen is just LIGHTER than the AIR so, it is not INERT GAS, not like other Noble Gases.
