Valence bond theory states that overlap between two atomic orbitals forms a covalent bond between two atoms.Valence bond and molecular orbital theories are used to explain chemical bonding.
Two atoms that have unpaired electrons in their orbitals can overlap to give rise to a chemical bond.
A sigma bond (σσ) forms when two atomic orbitals overlap between the nuclei of two atoms (also known as the internuclear axis ).
Pi bonds (ππ) occur when two atomic orbitals overlap outside of the space between the nuclei (outside of the internuclear axis).
The strongest bonds form with maximum overlap between orbitals.
In chemistry, valence bond (VB) theory is one of two basic theories—along with molecular orbital (MO) theory—that use quantum mechanics to explain chemical bonding. According to VB theory, a covalent bond forms from the physical overlap of half-filled valence orbitals in two atoms.
