How is simple cubic unit cell formed ? Calculate the number of atoms in a simple unit cell.

How is a simple cubic unit cell formed ? Calculate the number of atoms present in it.

Calculate the number of atoms in a face centred cubic unit cell.

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) .

The unit cell of a simple cubic system has atoms at the eight corners. Hence, number of atoms in an unit cell is

In a simple or primitive unit cell, what is the number of atoms per unit cell ?
