Question

What do you mean by metallic character? How does it differ down the group?​

Answer 1

Answer:

Metallic character increases down a group due to increase in atomic size. Thus, the outermost electrons are farther away from the nucleus and therefore can be lost easily. Hence, the electropositive character or metallic character increases. Non-metallic character decreases down a group due to increase in atomic size.

Answer 2

Answer:

From right to left across a period, metallic character increases because the attraction between valence electron and the nucleus is weaker, enabling an easier loss of electrons. Metallic character increases as you move down a group because the atomic size is increasing.

Hence option A is correct answer.
