Packing constituents in Crystal (1) Close packing in crystalline solids Close packing in two dimensions (a) Square close packing : In which the spheres in the adjacent row lie just one over the other and show a horizontal as well as vertical alignment and form square. Each sphere in this arrangement is in contact with four spheres. (b) Hexagonal close packing : In which the spheres in every second

Close packing in crystalline solids : In the formation of crystals,  the constituent particles (atoms, ions or molecules) get closely packed together. The closely packed arrangement is that in which maximum available space is occupied. This corresponds to a state of maximum density. The closer the packing, the greater is the stability of the packed system. It is of two types
