Crystals chemistry definition

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. WebWhat are crystals? Crystals are solids in which all of the atoms are arranged in a repeating pattern. These highly-ordered atoms form a structure known as a crystal lattice which extends in all 3D directions. …
