Formation of coloured ions

Transition metal ions can be identified by their colour Why transition metals form coloured complexes? 1. Complexes shows different energy levels for its d electrons due to d orbital splitting. Metal ions, with incompletely filled d sub-orbitals, experience energetic splitting of their five d sub-orbitals upon binding with ligands. Two groups of d sub-orbitals are formed: one group will be
