WebThe properties of crystals are related to the symmetry with which the atoms are arranged in the lattice. In the geometric sense, a figure is symmetrical if, when moved in a certain way, it looks as if it has not been moved. The different kinds of symmetry are defined by the way an object may be moved and yet seem to remain the same. WebCrystal symmetry is the ability of a geometrical element of a crystal (face, vertex, edge) to be superimposed on itself in several different ways. Crystal symmetry is visible on crystals. © DR.
