Question

explain in brief fcc crystal total four partical in each unit cell​

Answer 1

Answer:

4 atoms

The face-centered cubic (fcc) has a coordination number of 12 and contains 4 atoms per unit cell. The body-centered cubic (bcc) has a coordination number of 8 and contains 2 atoms per unit cel

Answer 2

Answer:

The no. of particles (atoms) per units cell in a FCC crystal lattice is 4.

A fcc unit cell has atoms present at 8 corners and 6 face centers. Each atom at corner is shared by 8 unit cells. Hence, it contributes one eight to a unit cell. Each atom at face center is shared by 2 unit cells. Hence, it contributes one half to a unit cell.
