Question

Calculate the number of atoms in fcc
unit cell.​

Answer 1

Explanation:

now similarly each face centre contributes to two unit cells now contribution per unit cell by six face centres is equal to 1/2*6=3 atoms…so hence total no. Of atoms per unit cell of FCC lattice is (1+3)= 4 atoms..

Answer 2

Answer:

12

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 cell.
