Statement I: In a closest packed structure, the number of octahedral voids is equal to the number of — Solid State Chemistry Question

💡 Solution & Explanation

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.
