Modern light bulb filaments are usually Tungsten not Carbon. However early bulbs used things like silk coated with Carbon. Filament means thin thread. The bulbs are filled with inert gas like Argon to stop the filament from burning up with oxygen. Arc lamps use Carbon rods though.

What elements are in light bulbs as a filament?

Light bulb filaments are usually made of tungsten, which has a very high melting point. Occasionally carbon is used as a filament.


What is the function of the Tungsten filament in a light bulb?

Because it has a very very high melting temperature: 6191F, 3422C. However it is also very difficult to work with, so early light bulbs used carbon for making the filament instead. Around the year 1900, carbon filaments were replaced with tantalum filaments. It was not until about 1910 that it became practical to make tungsten filaments.


Is light bulbs organic or inorganic?

Light bulbs are considered inorganic as they are primarily made from materials like glass, metal, and various chemicals that do not contain carbon-hydrogen bonds typical of organic compounds. The components, such as tungsten filaments or phosphors in LED bulbs, are derived from mineral sources and do not originate from living organisms. Therefore, light bulbs fall under the category of inorganic materials.
