Atoms in a covalent bond are usually much stable as a result of them

achieving the octet configuration. Energy is thereby required to break the

bonds in order to permit the interaction of the electrons of the substances

involved.

The interaction of the electrons is what acts as a precursor in the formation

of new products.
