Question

(B) $1$. Frenkel defect occurs in ionic crystals where there is a large difference in the size of ions. The smaller ion (usually cation) is dislocated

Vedclass · Accepted Answer

Frenkel defect is a dislocation effect

Vedclass · Answer

(B) $1$. Frenkel defect occurs in ionic crystals where there is a large difference in the size of ions. The smaller ion (usually cation) is dislocated from its lattice site to an interstitial site. Thus,statement $B$ is correct,and statement $A$ is incorrect.$2$. Paramagnetic substances are weakly attracted by a magnetic field,not repelled. Thus,statement $C$ is incorrect.$3$. Schottky defect involves the missing of equal numbers of cations and anions from the lattice,which decreases the density of the crystal. Thus,it affects the physical properties of solids. Statement $D$ is incorrect.$4$. Therefore,the only correct statement is $B$.

The correct statement$(s)$ regarding defects in solids is/are:
