In which type of ionic substances is the Frenkel defect commonly observed?
Options
- AIonic substances with similar ion sizes
- BIonic substances with a large difference in ion sizes
- CIonic substances with covalent bonding
- DIonic substances with metallic properties
Correct answer
B. Ionic substances with a large difference in ion sizes
Step-by-step solution
The Frenkel defect is commonly observed in ionic substances with a large difference in ion sizes, such as ZnS, AgCl, AgBr, and AgI due to the small size of certain ions like Zn2+ and Ag+.
