We use inert gas. Why answer is fifth group element not inert gas e.g. Helium.

I think in electrical bulb filled Argon gas.

Because that gas makes it colorful light bulb.

Filling a bulb with an inert gas such as argon or nitrogen retards the evaporation of the tungsten filament compared to operating it in a vacuum.

What will happen if the electric bulb is filled with oxygen gas?

Filament is made of nichrome and inert gas will not react with this.

Filament is made of tungsten and nichrome. If any other gas instead of noble gas or inert gas (noble gases are in the last column of the periodic table) was used, the filament would overheat and blast.

Well. I thought argon was used in the bulb, and the filament is made up of tungsten.

Why would a bulb catch fire without oxygen and can even blast if it is not filled with inert nonreactive gas?
My science teacher confused me by asking this question and I answered to prevent oxidising.
