Question

Coordination number in BCC crystals is

• A. 6
• B. 4
• C. 8
• D. 12

Hint:

Remember: BCC = 8, FCC = 12, Simple Cubic = 6 (coordination numbers).

Answer 1

The Correct Option is C

Step 1: Understanding coordination number.
The coordination number is the number of nearest neighboring atoms surrounding a given atom in a crystal structure.
Step 2: Structure of BCC crystal.
In a Body-Centered Cubic (BCC) structure, each atom at the center of the cube is surrounded by atoms located at the eight corners of the cube.
Step 3: Counting nearest neighbors.
Each atom in a BCC lattice has eight nearest neighboring atoms at equal distances.
Step 4: Conclusion.
Therefore, the coordination number of a BCC crystal is 8.
