It was filled for the long life of the bulb.

Because of its coolness property.

Nitrogen could be an answer, but most appropriate answer will be Argon gas.

Yes nitrogen gas is usually used in electric bulb

Nitrogen gas is used because it is more stable than other gases in option.

I totally agree with Hemant garg....

We do not use hydrogen because hydrogen is very inflammable gas and it caches fire immediately when is in the contact with a little spark.

We do not use oxygen gas because this gas is responsible for the combustion process and it helps the fire to burn more.so,we can't use oxygen gas.

Now carbon dioxide gas is not used in bulbs because carbon dioxide gas is not helpful for combustion of fire.

Now nitrogen gas is used in bulbs because when we see in periodic table nitrogen gas is on 7th no. so, it's atomic no. is seven. if we write the electronic configuration of nitrogen we see that his outer orbital is half filled and it,s more stable than other gases that are given in the options. this nitrogen gas molecules glow and emit radiations when current passes through it.

Oygen is not used because it burns the filament in the bulb, made of mercury so except oxygen we can use other gases but commonly inert gases are used to fill the bulbs.

Other than nitrogen which gases are used.

I also think that argon is used to fill the bulb
