What is the formula of a compound in which the element Y forms hcp lattice and atoms of X occupy 2/3rd of tetrahedral voids?
The number of tetrahedral voids formed is equal to twice the number of atoms of element Y. But only 2/3 of these tetrahedral voids are occupied by atoms of element X.

WHY IS FRENKEL DEFECT NOT FOUND IN PURE ALKALI METAL HALIDES?
Frenkel defect is not found in pure alkali metal halides. This is because of the larger size of the cations of the alkali metals, due to the large size the cations cannot fit into the interstitial sites.

calculate the distance between Na+ & Cl- ions in NaCl crystal if its density is 2.165 g cm-3.(molar mass of NaCl+58.5 g mol-1.)
Since there are 2N ions in one gram molecule,
The mass associated with each ion = M/2N
pd3 = M/2N
