Question

in which type of crystal defect the density of crystal decreases ? explain with diagram.​

Answer 1

Explanation:

schottky defeat is the answer

Answer 2

The crystal defect in which the density of the crystal decreases is Schottky defect.

Explanation:

• In ionic crystals, two types of defects are observed - Frenkel defect and Schottky defect.
• In Frenkel defect, a cation is dislocated from its normal position and occupies an interstitial site. This type of defect does not result in a change in the density of the crystal.
• In Schottky's defect, cations and anions are missing from the crystal. The number of cations and anions missing is the same in order to maintain electrical neutrality.
• As the ions are missing from the crystal, it results in a decrease in the density of the crystal.
• It can be explained with the help of the diagram given in the attachment.
