Webfree-atom (in covalent solids) or free-ion (in ionic and metallic solids) potentials. This approximation fails completely when the crystalline environment strongly changes the free-atom character of the potential at a given atomic site. These effects may occur in several systems, such as (0 solids where strong ionic-covalent bonding occurs

Ionic solids, such as sodium chloride and nickel oxide, are composed of positive and negative ions that are held together by electrostatic attractions, which can be quite strong ().Many ionic crystals also have high melting points. This is due to the very strong attractions between the ions—in ionic compounds, the attractions between full …
