WebApr 13, 2013 · You are absolutely correct, it all about the metal's electrons and also about their d orbitals. Transition elements are usually characterised by having d orbitals. Now when the metal is not bonded to anything else, these d orbitals are degenerate, meaning that they all have the same energy level. WebFurthermore, a crystal can contain mixtures of these elements (e.g,. Mn and Fe) and these can participate in charge transfer. Energy is absorbed from visible light to transfer electrons from one atom to another. For example: A crystal contains metals (M) in two oxidation states: M2+ and M4+ M2+ can loose an electron and become M3+
