Each overlapping atomic … WebAccording to the valence bond theory, a chemical bond is formed when the overlapping atomic orbitals of the involved atoms. Due to the overlapping, electrons are most likely to be in the bond region. Bonds are viewed as weakly connected orbitals in the Valence bond theory (small overlap).
WebPostulates of valence bond theory are: A covalent bond is formed by overlapping of orbitals having two unpaired electrons of opposite spins. When the overlapping between the orbitals is greater, the covalent bond formed is stronger. When a covalent bond is formed, the energy of the molecule decreases and the molecule becomes more stable.
