Actually most of the electrical bulbs filled with neon atomic number 10. But I don't see nitrogen filled bulbs. Why?

Argon has filled in an electric bulb.

Inert gases are used.

At the same time, the pressure of Argon gas would almost prevent 'evaporation' of the filament. Modern bulbs are usually filled with a mixture of argon and nitrogen.
More rarely, some bulbs are filled with pure argon, krypton or xenon. The earliest bulbs weren't filled with any gas but had the vacuum inside.

I agree nitrogen is used inside the electric bulb.
But why another gases doesn't use?

Nitrogen.
- It prevents the entry of oxygen so that the filament doesn't oxidize too quickly and become unfunctional. Many people have the wrong idea about the Electric bulbs that there is no vacuum in the electric bulb.
- Actually, argon gas or argon gas mixed with a little nitrogen is filled in the bulb under some pressure.

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.

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

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.
