Part of the periodic table is shown. The letters are not the symbols 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 V
- C. Y has a lower melting point than V
- D. Z is more reactive than X
Explanation
A. Reactivity for metals increases down the group so V is less reactive than Y which is below V.B. Metallic character decreases as we go from left to right so W has less metallic character than V.C. Melting point for Group I-IV increases across the period and decreases down the group. Y being below V will have a lower melting point. Hence Option C is correct.D. Reactivity decreases down the group for halogens and nonmetals.

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.
