In ccp arrangement the pattern of successive layers can be designated as

Packing refers to the arrangement of constituent units in such a way that the forces of attraction among the constituent particles is maximum and the constituents occupy the maximum available space. In two dimension there are square close packing and hexagonal close packing, cubic close packing and body-centred cubic packing i) hcp: AB AB AB AB .... arrangement Coordination no. = 12 , % occupied space = 74% ii) ccp: ABC ABC ....... arrangement Coordination no. = 12, % occupied space = 74% iii) bec: 68% space is occupied. Coordination no= 8 17. The pattern of successive layers of cop arrange-ment can be designated as

Packing refers to the arrangement of constituent units in such a way that the forces of attraction among the constituent particles is the maximum and the contituents occupy the maximum available space. In two dimensions, there are hexagonal close packing and cubic close packing. In three dimentions, there are hexagonal, cubic as well as body centred close packings. The pattern of successive layers in ccp arrangement is:
