Valence Bond theory

This theory was proposed by Linus Pauling. He was awarded the Nobel  Prize for Chemistry in 1954. The theory was very widely used in the period 1940-1960. It provides a basis for simple description of small inorganic molecules.  Atoms with unpaired electrons tend to combine with other atoms which also have an unpaired electrons. In this way the unpaired electrons are paired
up, and the atoms involved all attain a stable electronic arrangement. This is usually a foll shell of electrons ( a noble gas configuration). Two
electrons shared between two atoms constitute a bond. The Number of Bond is formed by an atom is usually the same as the number of unpaired
electrons in the ground state.
