Web8 nov. 2024 · Valance Bond theory describes chemical bonding in determining the shapes of molecules. It states that when half-filled orbitals of two atoms overlap, the electrons paired up as a result of this overlap. Thus, a covalent bond is formed. The bond strength depends on the overlapping of orbitals. Larger the overlap, the more powerful the bond is.
