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

Argon is used in an electric bulbs.

Argon Is Used.

Argon is a commonly used gas used to fill incandescent light bulbs. It increases bulb life by preventing the tungsten filaments from deteriorating too quickly. Other gasses such as helium, neon, nitrogen, and krypton are also used in lighting.

NITROGEN is very LESS REACTIVE in nature, we know it as it is popular to reduce oxygen's activity in the air, thus, it is the perfect alternative for NEON or ARGON to be filled up in bulbs.

Filament is made of tungsten and when the bulb is on a lot of heat is produced so that no gaseous combustion which may lead to explosion takes place least reactive nitrogen in this case can be used.

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.
