Why does Schottky defect decrease the desity of a crystal ?

Schottky defect is-

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

In the Schottky defect:

What is the effect of Schottky defect on the density of crystal ?

Which defect causes decreases in the density of crystal?

Which defect causes decreases in the density of crystal?

Schottky defect lowers the density of ionic crystals while Frenkel defect does not. Why?

Schottky defect lowers the density of ionic crystals while Frenkel defect does not. Discuss.

Ionic lattic has two major points defects ,(1) Schottky (2) Frenkel defects . Schottkly defects occurs due to the cations - anion pair's missing from the lattice sites . Frenkel defects occurs when cation leaves its lattice site and fits into an interstitial space. The neutrality of the crystal is being maintained and we considered all losses from interstitial positions. which defect decrease density of the crystal ?

Examine the defective crystal given below and answer the question that follows : State if the above defect is stoichiometric or non-stoichiometric. How does this defect affect the density of the crystal ? Also, write the term used for this type of defect.
