Answer 2

The correct answer is option (a) a/2.

Explanation:

• a/2 is the atomic radius of a BCC crystal structure.
• BCC stands for body-centred cubic structure.
• The unit cell of BCC consists os spheres in the corners of a cube and one sphere in the centre of the cube.
• It can be obtained by adding a second lattice point at the center of each cubic cell of a simple cubic lattice.
• Therefore, the unit cell of each bcc lattice can be considered as two interpenetrating simple cubic primitive lattices.
