What is the difference between body centred cubic and face centred cubic?

If 'a' stands for the edge length of the cubic systems: simple cubic, body centered cubic and face centred cubic, then the ratio of radii of the spheres in these systems will be respectively. 2.

If ‘a’ is the length of the side of a cubic unit cell the distance between the body-centred atom and the corner atom in the cube will be

Calculate the number(n) of atoms contained within (i) a primitive cubic unit cell (ii) a body –centred cubic unit cell and (iii) a face-centred cubic (f.c.c) unit cell

Distinguish between face-centred and end-centred unit cells .

How many atoms are there per unit cell in (i) simple cubic arrangement of atoms, (ii) body centred cubicarrangement of atoms, and (iii) face-centred cubic arrangement of atoms?

The packing fraction for a body centred cube

The packing efficiency of simple cubic (sc.) body centred cubic (bcc) and cubic close packing (ccp) lattices follow the order

Place the atoms of an element 'A' in the lattice points of Face centred cubic structrue.

Percentage of free space in a body-centred cubic unit cell is

Calculate the efficiency of the packaing in case of face - centered cubic crystal .
