ValenceBondBindung
ValenceBondBindung, often shortened to VB theory, is a fundamental concept in chemistry that explains chemical bonding. It was developed by Walter Heitler and Fritz London in 1927 and later expanded upon by Linus Pauling and John C. Slater. VB theory describes a covalent bond as a result of the overlap of atomic orbitals. When two atoms approach each other, their atomic orbitals containing unpaired electrons can overlap. This overlap allows the electrons to be shared between the two atomic nuclei, forming a stable bond. The greater the overlap, the stronger the bond.
This theory also introduces the concept of hybridization, where atomic orbitals mix to form new hybrid orbitals.
Valence bond theory successfully explains the formation of many covalent bonds and molecular geometries. It provides
