Answer 1

Answer:

Tungsten because it have high melting point

Explanation:

Answer 2

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.

Pure Tungsten is one such element used for making bulb filament as it has the highest melting point of 3695K. Also, its vapour pressure is very low and has great tensile strength out of all the metals used to conduct heat and electricity. -The chemical symbol of Tungsten is W which comes from Wolfram.
