Explanation:
Main reason why electric bulb is filled with nitrogen or argon instead of air is that the bulb contains closed glass chamber with inactive (inert) gas called Argon. Glass chamber in bulb gets filled with the air with presence of oxygen causing filament to burn to react with oxygen. Glass chamber are not made vacuum.

Explanation:
1)Air contains oxygen which is a supporter of combustion.
2) When the bulb glows the filament is at a temperature of 2700 degree Celsius, which is the ignition temperature of combustion.
3)So to avoid combustion of filament, chemically unreactive gas nitrogen and argon are filled in the bulb
