      in crystallography, any of a set of lines used to describe the orderly arrangement of atoms in a crystal. If each atom or group of atoms is represented by a dot, or lattice point, and these points are connected, the resulting lattice may be divided into a number of identical blocks, or unit cells. The intersecting edges of one of these unit cells are chosen as the crystallographic axes, and their lengths are called lattice constants. The relative lengths of these edges and the angles between them place the solid into one of the seven crystal systems. (See crystal (silica mineral).) The position of an atom within a unit cell is given in terms of the crystallographic axes, and planes in the crystal are described using the axes.
