[/cs_text][cs_text]
- The different colours of the complexes are due to the fact that energies of the d orbitals are effected by
- The metal ion
- Surrounding ligand groups
- These energy separations of the d orbital result in
- Differences to which frequencies of photons absorbed
- Hence differences to colour
- Complexes that have no d electrons or 10 d electrons cannot absorb visible light and hence are colourless
- Zn2+ and Sc3+
