Why mangenese is transition metal?

Manganese is considered a transition metal because it is found in the d-block of the Periodic Table and has partially filled d-orbitals in its elemental and ionic forms. This characteristic allows manganese to exhibit various oxidation states, typically ranging from +2 to +7, and participate in complex formation and catalytic processes. Additionally, it shares typical properties of transition metals, such as the ability to form colored compounds and conduct electricity.
