Valence Bond Model of Covalent Bonding
Bond formation is driven by the interactions the valence electrons of the atoms which make up the molecule.

This module reviews some of the properties of electrons in atoms and the nature of the possible overlaps of atomic orbitals which may lead to covalent bond formation. Descriptions of diatomic molecules develop from simple Lewis structures to sigma- and pi-bond formation in multiply bonded systems.
