Atomic Bonding The mechanisms of bonding between the atoms are based on the foregoing discussion on electrostatic interatomic interaction. The types of bond and bond strength are determined by the electronic structures of the atoms involved. The valence electrons take part in bonding. The atoms involved acquire, loose or share valence electrons to achieve the lowest energy or stable configuration of noble gases. Atomic bonding can be broadly classified as primary bonding secondary bonding Atomic Bonding Primary Bonds Three types primary bonds are found in solids Ionic Covalent Metallic Majority of the engineering materials consist of one of these bonds. Many properties of the materials depend on the specific kind of bond and the bond energy. 1.Ionic Bond Ionic bonds are generally found in compounds composed of metal and non-metal and arise out of electrostatic attraction between oppositely charged atoms (ions).
