Question

From top to bottom in a group of periodic table, the electropositive character of the elements

• A. increases
• B. decreases
• C. remains unchanged
• D. changes irregularly

Answer 1

The correct option is A

increases

Explanation for correct option:

(A) increases

Trend for electropositive character:

• Metals have the tendency to lose electrons, thus they are electropositive in nature.
• The metallic character of elements typically increases down the group.
• On moving down in a particular group, as the number of shells increases, the atomic radius increases, and so as the metallic character.
• Thus, the electropositive character increases down the group.

Hence, the correct option is (A).

Explanation for incorrect options:

Since, the electropositive character increases on moving from top to bottom in a periodic table. Thus, all the other options (B), (C), and (D) stand incorrect.

Therefore, option (A) is correct. The electropositive character of the elements increases from top to bottom.
