The number of close neighbors in a body centred cubic lattice of identical spheres is:
Open in App
Solution
The correct option is D 8
Actually, the unit we draw is more than a unit cell. We use the centre of the atoms (or spheres) to represent the corners of the unit cell, and each of these atoms are shared by 8 unit cells. There is a whole atom located in the centre of the unit cell. Thus each atom has 8 close neighbors
