close packing

Assertion . Hexagonal close packing is equally closely packed than cubic close packing . Reason. Hexagonal close packing has a corrdination number of 12 whereas cubic close packing has a coordination number of 8.

Three-dimensional close packing in solids is referred to as stacking the second square closed packing exactly above the first. In this tight packing, the spheres are horizontally and vertically correctly balanced. Similarly, we can obtain a simple cubic lattice by adding more layers, one above the other. This can be done in two ways. Three-dimensional close packing from two-dimensional square close-packed layers: By putting the second square closed packing exactly above the first, it is possible to form three-dimensional close packing. In this tight packing, the spheres are horizontally and vertically correctly balanced. Similarly, we can obtain a simple cubic lattice by adding more layers, one above the other.Three-dimensional close packing from two-dimensional hexagonal close-packed layers: With the assistance, of two-dimensional hexagonal packed layers, three-dimensional close packing can be obtained. The coordination number of cubic closed packing is:

The correct statement about zns crystal is:

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 empty space left in hcp packing is:
