The number of next nearest neighbours around each particle in face-centred cubic lattice is

A

4

B

6

C

8

D

12

Text Solution

Verified by Experts

The correct Answer is:
D
If we consider a face–centered particle . F. as shown in the figure then F is connected to 4 particles in its face, 4 particles in the adjacent faces of unit cell A and 4 particles in the adjacent faces of unit cell B. So the number of nearest neighbour particles =`4+4+4=12`.
