Question

Alkali metals have the biggest atomic radii.

(a) true

(b) false

This question was posed to me in an internship interview.

My question is taken from s-Block Elements topic in section s-Block Elements of Chemistry – Class 11

Answer 1

Correct choice is (a) true

Easy explanation: The alkali metals have the biggest atomic radii in their respective periods, atomic radii increases as we go down the group due to the addition of a new shell in each subsequent step. So the above statement is true.
