Solid State Chapter Solids are commonly isolated into three extensive classes—crystalline, noncrystalline, and quasicrystalline. The type of bonding in crystalline solids, they are classified as Ionic solids, molecular solids, covalent (or network) solids and metallic solids. Amorphous solids do not have definite geometrical shape and are often referred to as pseudo solids. Solids show electrical, magnetic and dielectric properties. Such properties depend upon the features of the atoms that structure the solid, on the way those atoms are organized, and on the forces between them.
