How does the size of a divalent metal ion vary with the number of d electrons?...
How does the size of a divalent metal ion vary with the number of d electrons? Explain. How does the size of a metal ion change with its oxidation state? Explain. Why is metal ion size important in bioinorganic chemistry?
Homework Answers
Let us consider 3d series element,all are divalent metals,as we
increase the d electron,nuclear charge also increase so the size of
metals decrease till de configuration,but after d5,pairing of
electron in orbitals is taking place,so that the repulsion between
electron generate,it causes to the small increase in radius of
metals till 3d10 configuration.
