Which of the following always increases on going from top to bottom in a group ?
Correct answer: A. Metallic character
- A. Metallic character
- B. Electronegativity
- C. Oxidizing power
- D. Tendency to get reduced
Explanation
Metallic character generally increases down a group because atomic size and shielding increase, making the outer electron easier to remove. The likely mistake is choosing electronegativity, but electronegativity generally decreases down a group as attraction for bonding electrons becomes weaker.

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.
