The coordination number of an atom in a body-centered cubic structure is ____.
[Assume that the lattice is made up of atoms]
[Assume that the lattice is made up of atoms]
Answer: 8
Solution
In a body-centered cubic (BCC) structure, there is one atom at the center of the cube and eight atoms at the corners of the cube.
The central atom touches all eight corner atoms. Each corner atom is shared by eight unit cells, but from the perspective of the central atom, it is in direct contact with all eight corner atoms.
Therefore, the coordination number (the number of nearest neighbors) of an atom in a BCC structure is 8.
