WebSep 21, 2024 · Crystals are classified into general categories based on their shapes. A crystal is defined by its faces, which intersect one another at specific angles; these intersections are characteristic of the given substance. The seven crystal systems are shown below, along with an example of each. The scientific definition of a "crystal" is based on the microscopic arrangement of atoms inside it, called the crystal structure. A crystal is a solid where the atoms form a periodic arrangement.
