Question

In a group, basic nature __________ from top to bottom.

• A. increases
• B. decreases
• C. remains same
• D. none of these

Answer 1

The correct option is A increases

As we move down the group, the IE decreases and thus metallic character increases.

As a result, the basic character of the elements increases down the group with increasing metallic nature (decreases IE and increases size).

Thus In a group, basic nature increases from top to bottom.

Hence, the correct option is $\text{A}$
