Question

The number of close neighbours in a body-centred cubic lattice of identical spheres is:

• A. $4$
• B. $12$
• C. $6$
• D. $8$

Answer 1

Answer: (D)

$8$

The number of close neighbours in a body-centred cubic lattice of identical spheres is 8. In a body-centred cubic lattice, spheres are present at 8 corners of the cube and the body centre. The sphere at body centre is surrounded by eight spheres present at 8 corners.

Hence, option D is correct.
