Transition Metal Bonding Models

Funded under: FP5

Abstract

The physical and chemical properties of transition metals are strongly influenced by their partly filled d-shells. The atomic d-states interact to form a narrow band of energy levels, from bonding combinations of d-orbitals at low energies to anti-bonding combinations at the top of the energy bands. Cohesion arises from these partially filled energy bands, since the low energy bonding states fill first. There are always more states to be filled than there are electrons to fill them and transition metals are essentially very large unsaturated covalently bonded molecules.
