How the law of conservation of mass could be useful for investigating chemical changes

A covalent chemical bond is one in which outer-shell electrons of two atoms are shared so as to satisfactorily fill the outer electron shells of both atoms. protons and neutrons are shared by two atoms so as to satisfy the requirements of both atoms.
