Question

Statement I: In a closest packed structure, the number of octahedral voids is equal to the number of atoms present. Statement II: Octahedral voids are located midway between the two closest packed layers.

Correct answer: A. Statement I is correct: in any closest packed structure of N atoms, the number of octahedral voids is N. Statement II is also correct: the octahedral voids are created at the interstitial spaces between two close-packed layers, located exactly midway between them, which explains why there is 1 octahedral void per atom.
