A molecule is formed by interconnecting atoms of elements, the force that holds atoms together in a molecule is called chemical bonding. For example, two atoms of oxygen in a molecule of oxygen (O2) are chemically linked. Except for inert gas, the outer orbit of all other elements is temporary. Because they have less than eight electrons. Elements tend to acquire electrons in their outermost orbit like their nearest inert gas, so that it becomes permanent, which is why chemical cohesion occurs between the elements. Compounds with a valid additive bond are composed of ions with a positive and negative charge. These ions are attached to each other by a very strong stable lawful force and most of the covalent compounds are simply gas, liquid, or volatile solids. Let's know more about Chemical Bonding.
