The melting point of sulphur is higher than that of phosphorous because:
Correct answer: A. Sulphur has strong vander waal forces
- A. Sulphur has strong vander waal forces
- B. Sulphur has weak vander waal forces
- C. Phosphorous has strong vander waals forces
- D. None of these.
Explanation
Sulfur molecules have a larger number of electrons compared to phosphorus, leading to stronger van der Waals forces, which result in a higher melting point.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
