Verified By Collegedunia
The Correct Option is C
Solution and Explanation
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.
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.
