A thermodynamic explanation of this effect relies on low values of metal-ligand bond enthalpies and was outlined by Drago, but it is believed that this effect arises from the relativistic contraction in the Bohr atomic model.
This effect was first described by the same scientist who outlined the importance of dative bonds in coordination complexes, Nevil Sidgwick. A thermodynamic explanation of this effect relies on low values of metal-ligand bond enthalpies and was outlined by Drago, but it is believed that this effect arises from the relativistic contraction in the Bohr atomic model. This effect is used to explain why PbO is more stable than PbO2, why the +1 oxidation state of titanium is so common, and also explains why group 14 elements tend to form compounds in a +2 oxidation state. Occurring due to electrons pulling closer to heavier nuclei, for 10 points, name this effect in which heavier members of the p-block tend to have an oxidation number ? two less than their valency, due to a namesake group of two electrons not participating in bonding.
