what is the valence bond theory
Hey!
Valence bond theory or VB theory is a theory based on quantum mechanics that explains how chemical bonding works. In valence bond theory , the atomic orbitals of individual atoms are combined to form chemical bonds . The other major theory of chemical bonding is molecular orbital theory or MO theory .
Hope this answer helps!
1) Valence orbitals of atom overlap each other to form a bond.
2) A pair of electrons is present in overlapping orbitals.
3) Electron density is maximum around bonded atoms.
4) Degree of overlapping determines strength of the bond.
