Question

Why is there a huge difference in boiling and melting points of oxygen and sulphur?

Answer 1

Answer:

Oxygen is gas due to which the molecules are loosely bonded due to which less energy(heat) is required to break the molecules.

Sulfur exist in solid state as a non-metal since it is solid the molecules are tightly bonded therefore high amount of energy(heat) is required to break the molecules. Therefore oxygen have low melting point as compare to sulfur

Answer 2

Melting and boiling point depends onthe intermolecular forces of attraction between the molecules. ... Due to which Sulphur having stronger intermolecular forces has highermelting point and boiling point thanoxygen with weaker intermolecular forces.
