1.	In each of the compouds : NaCl , ZnS and CaF_2 , write (i) ions occupying the voids (ii)types of voids occupied (iii) fraction of voids occupied.
Answer» Solution :(a)`NaCl=Na^+`ions in all the OCTAHEDRAL VOIDS (b)`ZnS=Zn^(2+)` ions in alternate tetrahedral voids (C ) `CaF_2=F^-` ions INALL the tetrahedral voids.
