Passage / Comprehension
Three dimensional close packed structure can be generated by placing layers of two dimensional hexagonal close-packed, one over the other.
Which of the following is/are correct when the same metal will exist in FCC and HCP structure:
Options:(select one or more)
Answer:
A, B, C, D
Solution:
A) Density is same because packing efficiency = 74% in both → Correct
B) Coordination number is 12 in both structures → Correct
C) Packing fraction is same (0.74) → Correct
D) Number of tetrahedral voids per atom is same (2 per atom) → Correct
Thus, both structures have identical packing properties.
Final Answer: A, B, C, D
