An element crystallises in a b.c.c. lattice. Nearest and next nearest neighbours are respectively

A

8,8

B

8,6

C

6,8

D

6,6

Text Solution

Verified by Experts

The correct Answer is:
B
In a b.c.c. structure C.N. (Every atoms touches 8 other atoms, 4 in a layer below it and 4 in a layer above it )
However, there are 6 other atoms (in six adjacent cubic sites) which are only slightly away from it. Thus , these 6 atoms are the next nearest neighbours.
