Detailed Solution

The reason electric bulbs are filled with chemically inert nitrogen and argon is to prevent oxidation of Tungsten filament.
An electric bulb's filament is constructed of tungsten, which burns rapidly when it comes into contact with oxygen in the air. That's why inert gases like argon and nitrogen are utilized to fill an electric bulb. Here, an inert gas means they don’t react with anything. These gases interact chemically. As a result, bulbs are filled with chemically inactive Nitrogen or Argon gas to avoid tungsten filament oxidation.
