About Crystal Lattice
A crystal lattice is the regular three-dimensional arrangement of particles in a crystalline solid. The content includes lattice points, unit cells, coordination number, packing patterns, and the differences among ionic, metallic, molecular and covalent network crystals, which should not be confused with amorphous solids.
