WebSep 3, 2024 · Alkali halids do not show Frenkel defect because (a) cations and anions have almost equal size (b) there is a large difference in size of cations and anions (c) cations and anions have low coordination number (d) anions cannot be accommodated in voids Answer Question 8. The coordination number of Y will be in the XY types of crystal: (a) 6 … WebA. Frenkel defect: “This defect is shown by ionic solids. The smaller ion (usually cation) is dislocated from its normal site to an interstitial site.” B. Schottky defect: “It is basically a vacancy defect in ionic solids. In order to maintain electrical neutrality, the number of missing cations and anions are equal.” C. Interstitial defect:

WebApr 9, 2024 · A Frenkel defect or dislocation defect is a type of point defect in crystalline solids named after its discoverer Yakov Frenkel. The defect forms when an atom or … WebSep 17, 2024 · Answer: The answer is the option (ii) At low temperature, substance exists in solid state due to low thermal energy and hence decreased molecular motion, which in turn leads to strong intermolecular cohesive i.e., forces, which hold the constituent particles together. Hence, option b is correct. Question:2 install itunes latest version for windows 11
On the exact definitions of Frenkel and Schottky defects
WebApr 9, 2024 · The Frenkel defect occurs when the smaller atom or ion (usually cation) leaves its original place in the crystal lattice and creates a vacancy in the crystal lattice. The cation occupies another interstitial position in the crystal lattice. The density does not change when a Frenkel defect occurs. In crystallography, a Frenkel defect is a type of point defect in crystalline solids, named after its discoverer Yakov Frenkel. The defect forms when an atom or smaller ion (usually cation) leaves its place in the lattice, creating a vacancy and becomes an interstitial by lodging in a nearby location. In elemental systems, … See more Even though Frenkel defects involve only the migration of the ions within the crystal, the total volume and thus the density is not necessarily changed: in particular for close-packed systems, the lattice expansion due to … See more Frenkel defects are exhibited in ionic solids with a large size difference between the anion and cation (with the cation usually smaller due … See more • Kittel, Charles (2005).
