General Electronic configuration of d-block elements are as follows:
- $3d$ series - (Ar) ${\text{3}}{{\text{d}}^{1 - 10}}{\text{ 4}}{{\text{s}}^{1 - 2}}$
- $4d$ series - (Kr) ${\text{4}}{{\text{d}}^{1 - 10}}{\text{ 5}}{{\text{s}}^{1 - 2}}$
- $5d$ series - (Xe) ${\text{5}}{{\text{d}}^{1 - 10}}{\text{ 6}}{{\text{s}}^{1 - 2}}$
- $6d$ series - (Rn) ${\text{6}}{{\text{d}}^{1 - 10}}{\text{ 7}}{{\text{s}}^{1 - 2}}$
