Document Summary

11. 1: what a bonding theory should do. When the potential energy reaches its lowest value, the two h atoms combine into a h2 molecule through a covalent bond. The inter-nuclear distance corresponds to the bond length. The potential energy corresponds to the negative of the bond-dissociation energy. 11. 2: introduction to the valence-bond method: valence-bond method. A description of covalent bond formation in terms of atomic orbital overlap (interpenetration of two orbitals). Draw valence-shell orbital diagrams for the separate atoms. Sketch the orbitals of the central atom that is involved in the overlap. Complete the structure by bringing together the bonded atoms and representing the orbital overlap. Can be used to explain the geometry of molecules. Doesn"t describe the actual bonding and orbitals involved: basic valence bond theory. Can be used to explain the bonding of molecules. 11. 3: hybridization of atomic orbitals: hybridization. This is a mathematical process of replacing pure atomic orbitals with reformulated atomic orbitals for bonded atoms.
