i. ZnS shows Frenkel defect due to a large difference in size of Zn2+ ion and S2- ion.
ii. KCl shows Schottky defects, as the size of K+ ion is almost similar to that of Cl- ion.
iii. AgBr shows both Frenkel defect and Schottky defect.
Non-Stoichiometric hydrides are hydrogen-deficient compounds formed by the reaction of dihydrogen with d-block and f-block elements.
These hydrides do not follow the law of constant composition. For example: LaH2.87, YbH2.55, TiH1.5...
In the cuprous oxide (Cu2O) prepared in the laboratory, copper to oxygen ratio is slightly less than 2:1. This means that the number of Cu+ ions is slightly less than...
When a solid is heated, vacancy defect can arise. A solid crystal is said to have vacancy defect when some of the lattice sites are vacant. Vacancy defect leads to...
Answer: (2) Frenkel defect
In Frenkel defect, some of ion (usually cation due to their small size) missing from their correct position and occupies position in interstitial.
Frenkel defect result in arrangement of...
Hydrides which are deficient in hydrogen and in which the ratio of hydrogen to metal is fractional are called non-stoichiometric hydrides. This type of hydrides are formed by d-and f-block...
