What is the coordination number of a particle in fcc structure?
Options
- A12
- B2
- C4
- D6
Correct answer
A. 12
Step-by-step solution
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.
