In any transition series, from left to right, the d-orbitals are progressively filled and their properties vary accordingly.
Q. Which element do you expect to have the smallest atomic radius?

A

Sc

B

Zn

C

La

D

Hg

Text Solution

Verified by Experts

The correct Answer is:
B
Atomic size decreases along the transition series from left to right though at the end of the series, there is a slight increase. Down the group, the size increases through elements of the second and third series have nearly the same size due to lanthanide contraction.
