[...] Sodium chloride structure diagram 8 Sodium chloride has a face-centered cubic structure. This means that the structure of this ionic solid can be represented as a repetition of a geometric pattern (named unit cell) which here is cubic. To represent it, we draw a cube so that each of the corners and each of the midpoints of the faces contains a sodium ion and where each midpoint of the corner as well as the center of the unit cell contains chloride ions For the geometric vocabulary, the angle of divergence corresponds to the angle and the divergence coefficient is the length ratio between a line in the plane (for example ) and a line in the depth of the same measure (for example car on est dans a cube and all the edges are equal).
