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.

Explanation:
- as the filament of the bulb is made from tungsten. Argon is used because to stop the oxygen from light bulbs from corroding the hot tungsten filament . The use of argon in light bulbs prevents the evaporation of tungsten filaments, which results in increased light bulb life
