Explanation:
Detailed explanation-1: -Atomic radius increases down the group. This is due to an increase in the number of electron shells down the group.
Detailed explanation-2: -Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius.
Detailed explanation-3: -Reactivity of elements increases down the group as down the group number of shells increases and thus nuclear pull on the outermost electrons decreases.
