How bonding and structure are related to the properties of substances
Question
- A. They contain no charged particles
- B. The ions cannot move within the solid structure
- C. They are made of non-metal atoms
- D. They have low melting points
Answer
The correct option is The ions cannot move within the solid structure. This answer is correct because it matches the approved learning objective to explain why a solid ionic compound does not conduct electricity in the subtopic Properties of ionic compounds.
Explanation
The correct option is The ions cannot move within the solid structure. The ions cannot move within the solid structure is correct because it directly supports the approved learning objective to explain why a solid ionic compound does not conduct electricity. This belongs to the subtopic Properties of ionic compounds within How bonding and structure are related to the properties of substances, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Properties of ionic compounds.
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.
