What Are d Block Elements in Chemistry?

D-block elements, also known as transition metals, are a group of elements that occupy the d-block in the periodic table. They reside in the central part of the table, spanning groups 3 to 12 and periods 4 to 7. These elements play a pivotal role in various chemical reactions due to their electron configurations and variable oxidation states. For example, the element Chromium (Cr) has an electron configuration of [Ar] 4s1 3d5, where the last electron enters the 3d subshell. This unique arrangement leads to the forming of various oxidation states, a defining characteristic of these elements....

Why d Block Elements Are Called Transition Elements?

The name “transition elements” aptly describes the role of d-block elements in the periodic table. These elements act as a bridge, transitioning from the highly reactive s-block elements to the less reactive p-block elements. Their unique ability to exhibit multiple oxidation states and form complex compounds positions them as essential components in various chemical reactions....

Atomic Structure of d Block Elements

D-block elements has d subshell in their atomic structure. The presence of d-orbitals plays a pivotal role in influencing their chemical behaviour. D-block has a poor shielding effect thus there is net increase in electron nucleus attracting leading to the smaller size as compared to the alkali metals and alkaline earth metals. The d-orbitals’ relatively small energy differences enable multiple oxidation states and a variety of coordination geometries in complex compounds....
