“A chemical bond is an attractive force that holds a chemical species’ constituents together.”
For chemical bond formation, many theories have been proposed, including valence shell electron pair repulsion theory, electronic theory, molecular orbital theory, and valence bond theory.
The tendency of a system to achieve stability is credited with the formation of a chemical bond. The inertness of noble gases has been discovered to be a direct result of their completely filled outermost orbitals. As a result, it was proposed that elements with electron deficiency in their outermost shells are unstable. As a result, atoms combine and complete their separate octets or duplets to achieve the stable configuration of the nearest inert gases. As a result, this combination can happen either through the sharing of electrons. A covalent bond is a chemical bond that is formed as a result of atoms sharing electrons. A formed ionic bond is also the result of atoms sharing electrons.
