Crystal lattices

A crystal lattice is a highly ordered, repeating arrangement of atoms, ions, or molecules that forms the structure of a crystalline solid. Imagine a 3D grid where each point represents an atom, and this pattern repeats uniformly in all directions. This organized pattern determines the physical properties of the material, such as strength, melting point, and how it interacts with light. Common examples include salt, quartz, and diamonds. The regularity and symmetry of the lattice make crystals distinct and give them their characteristic appearance and behavior.
