Answer the following question.
What type of stoichiometric defect is shown by ZnS and why?
Frenkel defects are not found in alkali metal halides because ____________.
The following diagram shows:
Assertion: No compound has both Schottky and Frenkel defects.
Reason: Both defects change the density of the solid.
Assertion: Due to Frenkel defect, there is no effect on the density of the crystalline solid.
Reason: In Frenkel defect, no cation or anion leaves the crystal.
Which of the following crystals does not exhibit Frenkel defect?
Silver halides generally show:
Frenkel defect is also known as:
(i) stoichiometric defect
(ii) dislocation defect
(iii) impurity defect
(iv) non-stoichiometric defect
Why is FeO (s) not formed in stoichiometric composition?
Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion: In any ionic solid (MX) with Schottky defects, the number of positive and negative ions are same.
Reason: Equal number of cation and anion vacancies are present.
