" In hcp structure,the packing fraction is "

In hcp and bcc structure, the packing fractions are respectively :

Show that in ccp and hcp structure the packing efficiency is 74%.

Assertion : A crystal having fcc structure is more closely packed then a crystal having bcc structure Reason: packing fraction for fcc structure id double than that of bcc structure

In a hexagonal close packed (hcp) structure of spheres, the fraction of the volume occupied by the sphere is A. In a cubic close packed structure, the fraction is B . The relation for A and B is

For the given closed packed structure of a salt made of cation X and anion Y shown below(ions of only one face are shown for clarity), the packing fraction is

In a hexagonal close packed (hcp) structure of spheres, the fraction of the volume occupied by the sphere is A. In a cubic close packed structure the fraction is B. The relation for A and B is:
