Question
- A. They have delocalised electrons
- B. The ionic bonds are too weak
- C. The ions are not mobile
- D. They are insulators
Answer
The ions are not mobile
Explanation
In solid ionic compounds, the ions are held in a fixed position and cannot move, which is why they do not conduct electricity.
Common mistake
Misunderstanding Ionic Conductivity
Students often think that solid ionic compounds can conduct electricity because they contain charged ions.
Emphasize that in solid ionic compounds, ions are fixed in place within the lattice structure and cannot move to conduct electricity.
