PRIMITIVE AND CENTRED UNIT CELLS

In a unit cell, atoms A, B, C and D are present at comers, face centres, body - centre and edge - centre respectively in a cubic unit cell. The total number of atoms present per unit cell is

In a unit cell, atoms A, B, C and D are present at half of total corners, all face - centres, body - centre and one third of all edge - centres respectively. Then formula of unit cell is

Atoms A, B, C and D are present at corners, face centres, body centres and edge centres and respectively in a cubic unit cell. Find the formula of compound.

Atoms A, B, C and D are present at corners, face centres, body centres and edge centres and respectively in a cubic unit cell. Find the formula of compound.

Assertion:Face centred cubic cell has 4 atoms per unit cell. Reason:In fcc unit cell , there are 8 atoms at the corners and 6 atoms at face centres .

Atoms A,B,C and D are present at corners, face centres , body-centres and edge-centres respectively, in a cubic unit cell.if two atoms from corners and two from face-centres are removed, then what is the formula of compound ?

If atoms are removed from half of the edge-centred OV_(s) in RbBr , then the molecular formula of unit cell is

What is primitive cell ?

In hexagonal primitive unit cell, the Corner is shared by:
