Which point defect does not lowers density of a crystal.

Which point defect lowers the density of crystal ?

Why Frenkel defect does not change the density of AgCl crystal ?

Define point defects.

What is the effect of presence of Schottky defects on the density of the crystal?

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 smaller ion leaves from its lattic site and fits into an intersitial space.which defect decrease density of the crystal ?

Examine the given defective crystal? Answer the following questions: How is the density of the crystal affected by this defect?
