About Crystalline Solids
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
