FIX THIS: Part of periodic table is shown; the letters are not symbol of the elements.Which statement is correct?
Correct answer: C. Y has a lower melting point than V
- A. V is more reactive than Y
- B. W has more metallic character than Y
- C. Y has a lower melting point than V
- D. Option a and c both are correct
Explanation
the melting points of Group I elements (alkali metals) decrease as you move down the group. This trend occurs because as the number of electron shells increases, the atomic radius becomes larger, which reduces the attraction between the nuclei and the outer electrons. Consequently, the metallic bonds become weaker, leading to lower melting points.

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.
