1.	Which of the followings is not true about the ionic solids ?
Answer» BIGGER ions form THECLOSE packed STRUCTURE. Smaller ions occupy either the tetrahedral or the OCTAHEDRAL voids depending upon their size. Occupation of all the voids is not necessary The fecation of octahedral or tetradheral voids occupied depneds upon the radii of the ions occupying the voids. Solution :Tetrahedral voids are alwaysdouble than octahedral, VOID. Hence (d) is not true.
