can someone please explain the valence bond theory and are there any other bonding theories to explain how a bond is formed

thanks for any help

more or less the valence bond theory is e- defficient atoms pairing off with atoms that can make up the difference. its also called a covalent bond. covalent bond are the bonds in compounds that result from the sharing of one or more pairs of electrons. For example NaCl (Na+) + (Cl-). Na is positive because its missing an e- which means that the atom is not neutral because it now has 1 more p+ than e-s. so it joins with Cl which by the way is neg. becuz it has gained and e- and it shares with Na to make NaCl. now its neutral and has no charge becuz now it has just as many e- as protons. well something like that.
