उत्तर
The coordination number of atoms in bcc crystal lattice is 8.
Explanation:
The coordination number of an atom in a crystal lattice is the number of nearest-neighbour atoms to that atom. In a body-centred cubic (BCC) crystal lattice, each atom at the centre of the cube is surrounded by 8 corner atoms.
