Please help what material would make the best light bulb filament?

If Tungsten is an option, that would be the answer

Explanation:

The electrical energy is converted to heat and light energy by the resistor when current passes through it. Tungsten has a very high melting point, it is hard and high thermal stability. Thus, it makes the best bulb filament.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
