Answer:
The closed glass chamber of the bulb contains, an inactive (inert) gas, Argon. The glass chamber can't be filled with air as the presence of oxygen will cause the filament to burn, i.e. react with oxygen. ... An obviously, inert gas won't react with the filament. Nitrogen is also used like argon .

Reason for an electric light bulb not filled with air is as follows below
Explanation:
- When the air is filled with an electric lamp, the unusually warm tungsten filament fires quickly with atmospheric oxygen.
- Therefore, the electric lamp is filled with chemically unreactive gases, such as argon or nitrogen.
- This gas does not react with hot tungsten fibers, thus extending the length of the lamp filament. Thatswhy argon or nitrogen is filled in an electric bulb.
