WebLecture Crystallography - University of Notre Dame WebJul 19, 2024 · What all crystals have in common is an extremely well-organized molecular structure. In a crystal, all of the atoms (or ions) are arranged in a regular grid pattern. For example, in the case of table salt (NaCl), the crystals are made up of cubes of sodium (Na) ions and chlorine (Cl) ions. Each sodium ion is surrounded by six chlorine ions.
