The property that always increases on going from top to bottom in a group is (a) Metallic character.
Correct answer: A. Metallic character
- A. Metallic character
- B. Electronegativity
- C. Oxidizing power
- D. Tendency to get reduced
Explanation
Metallic character increases down a group as the number of electron shells increases, leading to weaker attractions between outer electrons and the nucleus.

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.
