“Chemical bond is an attractive force that bounds the constituents of a chemical species together.”
So many theories are suggested for chemical bond formation such as valence shell electron pair repulsion theory, electronic theory, molecular orbital theory, and valence bond theory.
Formation of chemical bond is credited to the tendency of system to achieve stability. It was noticed that inertness of noble gasses is direct result of their completely filled outermost orbitals. Consequently, it was proposed that the elements having deficiency of electronsinoutermost shells are unstable. Thus, atomscombine with one another and finish their separate octets or duplets to achieve the stable configuration of the closest inert gasses. So, thiscombination may occur either by sharing of electrons. The formed chemical bond is a result of sharing of electrons amongatoms is known as a covalent bond. Also a formed ionic bond is a result of sharing of electrons amongatoms.
