Valence Bond Theory

Explanation

Valence Bond Theory - Definition, Limitations & Types

Valence bond (VB) theory elucidates the chemical bonding between the two atoms. Similar to molecular orbital (MO) theory, it explains bonding using principles of quantum mechanics.

According to the valence bond theory, bonding is caused by the overlap of half-filled atomic orbitals. An atomic orbital is a physical region or space where an electron may be present or found, with a probability calculated from the proper mathematical form of the orbital. The two atoms share an unpaired electron of each other to form a filled orbital to create a hybrid orbital and bond together. Sigma bonds and pi bonds are a part of the valence bond theory.
