In a face centred cubic (f.c.c.) arrangement, the number of atoms per unit cell is

Aluminium metal has face centred cubic (f.c.c) structure. The number of 'Al' atoms per unit cell of the lattice is

Aluminium metal has face centred cubic (f.c.c) structure. The number of 'Al' atoms per unit cell of the lattice is

Aluminium metal has face centred cubic (fcc) structure. The number of 'Al' atoms per unit cell of the lattice is

Unit cells can be divided into two categories, primitive and centred unit cells. (a) Differentiate between unit cell and crystal lattice. (b) Calcualte the number of atoms per unit cell in the following: (i) body centred cubic unit cell (bcc) (ii) face centred cubic unit cell (fcc) .

In a face centred cubic cell, an atom at the face contributes to the unit cell "____________"
