WebIn science, a crystal is a certain type of solid object. Scientists describe matter , or everything that can be seen, according to the way it is made. All matter is made up of tiny parts called atoms and molecules. If those parts are arranged in a regular pattern then the object is a crystal. On the outside crystals have a regular pattern of ... WebA crystal form is a set of planar faces which are geometrically equivalent and whose spatial positions are related to one another by a specified set of symmetry operations. If one face of a crystal form is defined, the specified set of point symmetry operations will determine all of the other faces of the crystal form. ... For example, crystals ...
