Question

Assertion (A): The tendency of losing electrons increases down the Group.

Reason (R): The most reactive metal is placed at the top of Group 1.

पर्याय

• Both (A) and (R) are true, and (R) is the correct explanation of (A).

• Both (A) and (R) are true, and (R) is not the correct explanation of (A).

• (A) is true but (R) is false.

• (A) is false but (R) is true.

Answer 1

(A) is true but (R) is false.

Explanation:

The tendency to lose electrons, indicative of metallic nature, increases down the group due to the rise in atomic size and the diminished nuclear attraction on the outermost electrons. The most reactive metal should be placed near the bottom of the group, rather than at the top.
