It is nitrogen because it can easily absorb heat and can reject easily.

Because the filament of the bulb is made of nichrome and nitrogen does not react with nichrome.

It is an inert gas which do not react with hot filament of the bulb made up of tungsten & temperature is over 1500c.

Incandescent light bulbs heat a tungsten filament to extremely high temperatures. At such temperatures ordinary air would rapidly oxidize the filament and the bulb would burn out in seconds. Instead the bulbs are filled with argon, which is inert and will not react with the tungsten under any conditions.

Actually argon and helium use in electrical bulb in tube light on high pressure mercury gas.

Argon and helium are generally used in bulbs. Edison used nitrogen due to its inactivity.

Is helium used in bulbs?
Yatin Rathore said:

Yes helium can also used in electric bulb, because it is inert gas. Is nitrogen a inert gas?

Ya we used nitrogen but why, we also used argon?
