In Period 2 and Period 3 maximum melting point shown by elements:
Correct answer: D. Carbon and Silicon
- A. Nitrogen and Phosphorus
- B. Neon and Argon
- C. Lithium and Sodium
- D. Carbon and Silicon
Explanation
So in periods two and three, the highest melting point elements tend to be the metal elements with the most delocalized electrons.In period 2, Carbon has the highest melting point, whereas in period 3 silicon has the highest 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.
