Chemical bond: The attractive force which holds together the constituent atoms of chemical compounds is called chemical bond. Combination of atoms: It. is universal law of nature that systems with lower energy are more stable. So atoms combine to form a molecule because it has a· lower energy i.e., more stable. Modern concept of chemical bonding: The formation -of a …
