crystal structures

Crystal structures refer to the organized arrangement of atoms, ions, or molecules within a solid. These structures form when particles bond together in a repeating pattern, creating a stable, geometric shape. Common examples include table salt (sodium chloride), which forms a cubic shape, and quartz, which has a hexagonal structure. The specific arrangement of particles influences the material's properties, like strength, color, and melting point. By studying crystal structures, scientists gain insights into the behavior and characteristics of different materials, ranging from minerals to metals and even pharmaceuticals.
