Which element has the largest atomic radius?
a) as
b) n
c) p
d) sb

The correct answer is option D, Sb

Explanation:

Atomic radius of As = 185 pm

Atomic radius of N = 155 pm

Atomic radius of P = 195 pm

Atomic radius of Sb = 206 pm

If we arrange the following element on the basis of their atomic radius in the increasing order , we will get the following

N (155 pm) < As (185 pm) < P (195 pm) < Sb (206 pm)

Thus among all the given element Sb has the largest atomic radius
