Which of the following series of d-block elements exhibits the minimum deviation in electronic configuration ?

A

3d series

B

4d series

C

5d series

D

6d series

Text Solution

Verified by Experts

The correct Answer is:
D
It has only one deviation. The expected configuration of Rg is [Rn] `6d^(9) 7 s^(2)` but its actual configuration is [Rn] `6d^(10) 7s^(1)`. The maximum deviation occur in 4d series: Nb, Mo, Tc, Ru, Rh, Pd and Ag. On the other hand, both 3d series and 5d series each have two deviations `[Cr, Cu and Pt. Au]` respectively.
