Which of the following generally increases on going from top to bottom in a group?

Explanation

The correct answer is Metallic character. As you move from top to bottom in a group, elements tend to exhibit increased metallic character. This is because the atomic size increases, which results in a lower ionization energy and a greater ability to lose electrons, typical of metals.In contrast, Electronegativity generally decreases down a group as the atoms get larger and the valence electrons are further from the nucleus. Oxidizing behavior decreases down a group because elements become more metallic and less likely to accept electrons. While Reducing behavior might seem to increase as elements become more metallic, it is not the property that 'generally increases' as clearly as metallic character does.
