Colours of Transition Metal Ions in Aqueous Solution – …

Transition metal complexes are formed when transition metals are bonded to one or more neutral or negatively charged non-metal species, referred to as ‘ligands’. Without these bonds, all the d orbitals are equal in energy – however, once they are present, some d orbitals move to a higher energy than they were at before, whilst some move to a lower energy, creating an energy gap.
