Question

In the closest packing of atoms Note: OV stands for Octahedral voids and TV stands for Tetrahedral voids., The size of TV is greater than that of OV, The size of TV is smaller than that of OV, The size of TV is equal to that of OV, The size of TV may be greater or smaller or equal to that of OV depending upon the size of atoms

MARKS App · Accepted Answer

For a given radius of anion ( r - ) Radius ratio for OV and TV is as follows r ⊕ r - O V > r ⊕ r - T V F o r T V , r ⊕ r - = 0.225 - 0.414 F o r O V , r ⊕ r - = 0.414 - 0.732 Hence, size of OV is larger than that of TV.
