Common old-fashioned light bulbs are of the incandescent type (including halogen) with a tungsten filament glowing at about 3000 degrees C emitting black-body radiation (light and heat). Tungsten is used because it has the highest melting-point of all metals.
The other type of bulb is fluorescent, of various types like tubes and CFLs

It depends on the type of bulb. Tungsten is the most common element in light bulbs. But there are neon based bulbs also
That part of a light bulb that causes light to light up is called the filament, and it is typically made from tungsten.
The wire inside of an electrical light bulb is called a "filament". The word filament comes from the Latin word "filum" which means "thread". In various fields there are many different types of filaments with different uses, however the ones inside of light bulbs are made out of tungsten and work by super-heating by passing electricity through it.
