D-block Theory

The D-block theory explains how transition metals' d orbitals (a type of electron cloud) influence their properties. These d orbitals are located in a specific region of an atom and can hold electrons that determine characteristics like color, magnetism, and ability to form various compounds. In transition metals, these d electrons can move or change energy levels during chemical reactions, giving them versatile chemistry. The theory helps scientists understand and predict how these metals behave in different situations, such as in catalysts or alloys, by focusing on the role of these d electrons.
