A chemical bond refers to the attractive force that holds atoms together to form molecules or compounds. It results from the sharing, transferring, or redistribution of electrons between atoms in order to achieve a more stable electronic configuration. There are three main types of chemical bonds: covalent, ionic, and metallic. Covalent bonds involve the sharing of electrons, while ionic bonds involve the transfer of electrons between positively and negatively charged ions. Metallic bonds occur in metals and involve the delocalization of electrons among a lattice of positive ions.
