Molecular Orbital Theory. After the failure of the valence bond approach to explaining the para magnetism in o 2 molecule and also to explain the formation of odd electron species like h 2 another theory was proposed known as molecular orbital theory. When the energies differ greatly the bonding mode becomes ionic.

Quantum mechanics describes the spatial and energetic properties of electrons as molecular orbitals that surround two or mor. The molecular orbital model is by far the most productive of the various models of chemical bonding and serves as the basis for most quantiative calculations including those that lead to many of the computer generated images that you have seen elsewhere in these units. In mo theory molecular orbitals form by the overlap of atomic orbitals.
In molecular orbital theory electrons in a molecule are not assigned to individual chemical bonds between atoms but are treated as moving under the influence of the atomic nuclei in the whole molecule.
After the failure of the valence bond approach to explaining the para magnetism in o 2 molecule and also to explain the formation of odd electron species like h 2 another theory was proposed known as molecular orbital theory. Mo modeling is only valid when the atomic orbitals have comparable energy. It was proposed early in the 20th century. Molecular orbital theory is more powerful than valence bond theory because the orbitals reflect the geometry of the molecule to which they are applied.
