Chemical Bonding

Definition

Chemical bonding refers to the attraction between atoms that enables the formation of chemical compounds. This interaction can be due to the sharing or transferring of electrons, leading to the establishment of ionic, covalent, or metallic bonds. In the context of piezo-magnetoelectric composites, understanding chemical bonding is crucial as it influences material properties, including electrical and mechanical performance.
