MCQ
In a multi layered close$-$packed structure:
  • ✓
    there are twice as many tetrahedral holes as many close-packed atoms
  • B
    there are as many tetrahedral holes as many closed packed atoms
  • C
    there are twice as many octahedral holes as many close-packed atoms
  • D
    there are as many tetrahedral holes as many octahedral holes
✓

Answer

Correct option: A.
there are twice as many tetrahedral holes as many close-packed atoms
No. of octahedral holes $=$ No. of close packed atoms.
No. of Tetrahedral holes $= 2\times $ No. of close packed atoms.
Hence, in a multi$-$layered close$-$packed structure, there are twice as many tetrahedral holes as many close$-$packed atoms.
