What is the colour of the transition metal complex often due to ?
Related to the presence of unfilled/partially filled d oribitals and so to unpaired electron in the metal ion

What happens when a d-block compound absorbs light?
light is absorbed by an atom only if the energy of the light matches the energy gap between the 2 energy states in the atom. If it does , energy promoted to higher energy level. frequency of light energy depends on the energy difference btwn the 2

What 3 things does the colour of a TM complex depend on?
no. of d electrons present in TM metal ion, arrangement of ligand around ion-affects splitting of d sub-shell. the nature of the ligand-diff ligands have diff effect on relative energies of the d orbitals
