WebMar 31, 2024 · Additional Information: Frenkel defect doesn’t have any effect on the density, mass or volume of the crystal as in the defect migration of ions takes place within the crystal. So, density, mass and volume of the ionic crystal remain the same even after having the frenkel defect. WebMar 13, 2024 · Frenkel defect is also called dislocation defect. It does not change the density of the solid. Frenkel defect is shown by ionic substances in which there is a large difference in the size of ions, for example, ZnS, AgCl, AgBr and AgI due to the small size of Zn2+ and Ag+ ions.
WebIn Frenkel defect, an ion is displaced from its lattice place to an interstitial place. So, there is no loss or gain of ions in lattice structure. It involves only the migration of the ions … WebThere is no relationship between density of a crystal and defect present in it Solution: In Frenkel defect, ions get displaced from their original position and move to interstitial sites. Hence, there is no change in the density of the crystal.
WebOct 31, 2024 · A solid-state in the Frenkel defect has a low coordination number. The chemical nature of a substance is unaffected by this defect. Frenkel Defect maintains … WebSchottky defects have no effect on the density of crystalline solid. Frenkel defect decreases the density of crystalline solids. Frenkel defect is a dislocation defect. Frenkel defect is a dislocation defect. 1736 Views. Answer. 62. If the positions of Na + and Cl-are interchanged in NaCl , the crystal lattice with respect to Na + and CI-is:

WebApr 10, 2024 · Moreover, the Frenkel defect doesn’t change the density of the crystal because ions are still present and have not left the crystal. This is different from Schottky defects where the density of the crystal is reduced. Some ionic compounds, such as AgBr, exhibit both Schottky and Frenkel defects. top 10 red flags in a womanWebFrenkel defect can be regarded as the combination of vacancy defect and interstitial defect. c.
