(ii) Each octahedral voids is surrounded by 6 spherus and each sphere is surrounded by 6 octahedral voids. (iii) The number of tetrahedral voids in a closest-packed arrangement is twice the number of spheres. (iv) The number of octahedral voids in a closest-packed arrangement is equal to the number of spheres.A. (i), (ii)B. (iii), (iv)C. (i), (iii)D. (i), (ii), (iii), (iv) |

Answer» Correct Answer - 4 Tetrahedral voids are surrounded `4` spheres sitting at the corners of a regular tetrahedron and are present in `HCP`as well as `C CP`. for every sphere in the closest packed arrangement there is one octahedral void and two tetrahedral voids. The octahedral voids are larger than the tetradral voids. |
