Why tungsten is used in electric bulb?

$\huge\underline\bold\pink{Answer}$

Tungsten is used for making filament of an electric bulb due to the following reasons: Being an alloy it has a very high melting point. It has very high resistivity so it does not burn easily at room temperature. The lamp glows at high temperatures.

Answer 2

Answer:

Tungsten has a high melting point (3380°C). It does not melt at high temperatures. It retains as much of heat generated, so that it becomes very hot and emits light.

Also, it is quite flexible.
