Frenkel defects are not found in alkali metal halide. Why?

Solution

This is because alkali metal ions have larger size which cannot fit into interstitial sites .

Give the correct order of initials T (true) or F (False) for following statements: I. In an anti-fluorite structure, anions form FCC lattice and cations occupy all tetrahedral voids. II. If the radius of cations and anions are $$0.2\ \mathring A$$ and $$0.95\ \mathring A$$, then co-ordination number of cation in the crystal is $$4$$. III. An ion is transferred from a lattice site to an interstitial position in Frenkel defect. IV. Density of crystal always increases due to substitutional impurity defect.

Solid State

Density of a crystal decreases due to Schottky defect and remains constant due to Frankel defect. If true enter 1,else enter 0.

Solid State

Frenkel defect does not change the density of the ionic crystal whereas, Schottky defect lowers the density of ionic crystal. Give a reason.
