Atomic and Ionic Radiii of d Block Element
- Atomic and ionic radii of d-block elements decrease across a period due to increasing effective nuclear charge.
- Within a period, slight variations may occur due to changes in electron configuration and shielding effects.
- Across a group, atomic and ionic radii of d-block elements tend to increase due to the addition of new energy levels.
- Generally, d-block elements have smaller atomic and ionic radii compared to s-block and p-block elements due to higher effective nuclear charge and complex electron configurations.

Electronic Configuration of the d-block Elements
Electronic Configuration of the d-block elements are those that can be found in the contemporary periodic table from the third to the twelfth groups. These elements’ valence electrons are located in the d orbital. d-block elements are sometimes known as transition elements or transition metals. The 3d, 4d, and 5d orbitals are represented by the first three rows of the d block elements, respectively.
