Question

the number of atom in a body centers cubic (bcc) unit cell of a mono atomic elementary substance is equal to​

Answer 1

Answer:

Explanation:

In a body centred cubic unit cell, at the corners 8 atoms are present and one atom is occupied at the centre of the body. We know that 8 corner atoms contribute one atom (8×18=1) and one body centred atom belongs to only one unit cell. So, the total number of atoms in a body centred unit cell is 2.
