How is the pattern of spheres in the hexagonal close-packed (hcp) structure different from the face-centered cubic (fcc) structure?
Options
- AIn hcp, spheres are stacked directly on top of each other, while in fcc, they are in a staggered arrangement.
- BIn hcp, spheres are arranged in layers of ABAB..., while in fcc, spheres are arranged in layers of ABCABC....
- CIn hcp, spheres are arranged in a cubic lattice, while in fcc, they are arranged in a hexagonal lattice.
- DIn hcp, spheres are packed in a simple cubic arrangement, while in fcc, they are packed in a body-centered cub
Correct answer
B. In hcp, spheres are arranged in layers of ABAB..., while in fcc, spheres are arranged in layers of ABCABC....
Step-by-step solution
In hcp, spheres are arranged in layers of ABAB..., while in fcc, spheres are arranged in layers of ABCABC....
