+Crystalline forms describe solids where atoms, molecules, or ions are arranged in a highly ordered, repeating three-dimensional pattern. This intrinsic structural regularity grants them distinct physical properties, making them fundamental to fields like [Materials Science](/wiki/materials_science) and observed ubiquitously as natural [Minerals](/wiki/minerals).
