WebJul 4, 2024 · Crystals tend to have relatively sharp, well-defined melting points because all the component atoms, molecules, or ions are the same distance from the same number and type of neighbors; that is, the regularity of the crystalline lattice creates local environments that are the same. WebThe scientific definition of a crystal is based on its internal structure rather than its outward appearance. All matter on Earth is made up of atoms or, more frequently, combinations of atoms called molecules. If the molecules of a substance are arranged in a regular repeating pattern, the substance is a crystal.
