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

The structure is shown here represents :

Q. Assertion :Schottky defect is generally shown by the compounds with high co-ordination number. Reason: In Schottky defect, equal number of anions and cations are missing from their lattice sites.

Q. Assertion (A) : The density of crystal having Schottky defect is lowered.
Reason (R) : The crystals suffering from Schottky defect have same number of cations and anions missing from their normal lattice sites.

In metal excess defect, anions all missed from their lattice sites and they are occupied by electrons to maintain electrical neutrality. These sites occupied by electrons are called F-centers.

What is the effect of metal excess defect on density of the crystal?
