What is the coordination number of a particle in fcc structure?
- A 12
- B 2
- C 4
- D 6
Answer & Solution
Correct Answer
(A) 12
Step-by-step Solution
Detailed explanation
Each constituent particle in a fcc lattice is surrounded by 4 particles in the plane, 4 particles above it and 4 particles below it. Hence, the coordination number of an atom in a fcc lattice is 12.
