Nitrogen gas is less reactive than other given gases. Generally we use Argon & krypton is because they are inert gases. These are noble gases. Which doesn't react easily.

These gases are filled in bulb because filament present in bulb is Tungsten. These gases increase life of Tungsten filament. Tungsten has melting point above 3000 degree C.

Hence it is use in electric bulb. Nitrogen is 78% abundant on earth. So it is used in electric bulb.

Why don't we use vaccum in bulbs, it could be more effective and may be much cheaper.

I thing its uses neon and argon.

We can use any of inert gases, but we use nitrogen cause this is least reactive & cheaper than other gases.

Because nitrogen is inert gas doesn't easily reaction.

Nitrogen due to its stability due to its inert nature as well as less inflammable nature than oxygen.

Because of it's coolness.

Because inert gas does not react with the filament. So we use inert gas in making the bulb.

As we have no choice for argon so most appropriate answer will be nitrogen whereas gas generally used in bulb is argon.

Why are not fill other gas in the bulb?

Why fill Nitrogen and Argen gas in the bulb?
