Current Question (ID: 17992)

Question:

$\text{The correct statement regarding defects in a crystalline solid is:}$

Options:

1. $\text{Schottky defects have no effect on the density of crystalline solids.}$
2. $\text{Frenkel defects decrease the density of crystalline solids.}$
3. $\text{Frenkel defect is a dislocation defect.}$
4. $\text{Frenkel defect is found in halides of alkaline metals.}$

Solution:

$\text{HINT: The smaller ion (usually cation) is dislocated from its normal site to an interstitial site.}$ $\text{Explanation:}$ $\text{A Frenkel defect is another form of a point defect that is created when an atom or cation leaves its original place in the lattice structure to create a vacancy while occupying another interstitial position within the solid crystal.}$ $\text{In the Frenkel defect, the density of ionic solid remains the same. It is also known as a dislocation defect. For example, ZnS, AgCl, AgBr, and AgI.}$
