Calculate the number of particles present per unit cell in a B.C.C unit cell

Explanation

Body centred cubic lattice (bcc) contains 8 corner particles and one particle at the centre of the body.


• The contribution of corner atom to the unit cell is 1/8
• The contribution of body centre atom to the unit cell is 1.
`:.` Number of particles in the unit cell of bcc
`=( 8 xx (1)/(8))=1+1=2`
