Transition metal chemistry

The transition metals are d-block elements (Groups 3-12 of the Periodic Table) whose atoms have a partially filled d-orbital or that form cations with partially filled d-orbitals. This means that when we are considering the transition metals of Period 4, scandium and zinc are not classified as transition metals although they are d-block elements.
