Crystalline
solids are solids that have particles arranged in a regular, repeating
patterns. They are held together by uniform intermolecular forces. The faces
intersect at a specific angle that identifies that substance. They have
distinctive internal structures that in turn lead to distinctive flat surfaces.
These flat surfaces give a short rage order. When exposed to x – ray
diffractometers, they exhibit a distinctive pattern used to identify the
material. They give the same face when you turn a crystalline solid around. The answer is crystal.
