Question:
How many lattice points belong to a face-centered cubic unit cell?
How many lattice points belong to a face-centered cubic unit cell?
Show Hint
In FCC unit cells, the total number of lattice points is 4 due to contributions from corner atoms and face-centered atoms.

The Correct Option is C
Solution and Explanation
Step 1: Face-centered cubic (FCC) unit cell.
In a face-centered cubic unit cell, there is 1 lattice point at each corner of the cube and 1/2 of a lattice point at each face center. Thus, the total number of lattice points in an FCC unit cell is 4.
Step 2: Conclusion. Thus, the correct answer is 4 lattice points.
Step 2: Conclusion. Thus, the correct answer is 4 lattice points.
