How bonding and structure are related to the properties of substances

Question

A. The structure is too dense
B. The ions are fixed in a lattice
C. The compound is not ionic
D. The electrons are tightly bound

Answer

The correct option is The ions are fixed in a lattice. 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 are fixed in a lattice. The ions are fixed in a lattice 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.
