Oxygen and sulphur are both elements in Group 16 of the periodic table. (i) Oxygen gas consists of \( \mathrm{O}_{2} \) molecules. Solid sulphur consists of \( \mathrm{S}_{8} \) molecules. Oxygen melts at \( 55 \mathrm{~K} \), whereas sulphur melts at \( 386 \mathrm{~K} \). Using the concept of intermolecular forces, explain the difference between their melting points. Refer to BOTH elements in your answer. (3 marks)
