Yeah. Actually, argon gas is used in electric bulbs because it is an inert gas. A lot of heat is produced in the bulb. If any another gas is filled, gas inside the bulb react with water molecules in the air and will form compounds which can lead to an explosion. It can also cause in the short life period of bulbs. To avoid that situation inert gases like He, Ne, Ar are commonly used in bulbs. In olden times to avoid reaction evacuated bulbs were used. But after experiments, it was proven that inert gases filled bulbs have more longevity than that of evacuated bulbs.

What about Argon?

Why are the electric bulb filled with the mixture of inert gases at low pressure?

No reaction will happen here.

But actually, argon is used in electric bulb.

Yes, argon is used in bulbs.

Generally argon and krypton is filled in electric bulbs.

Yes, you are right @Bhupendra Kumar.

It should be Argon (Ar).

Why the nitrogen is used in bulb?
