Question
- A. The type of ions involved.
- B. The electrostatic forces between ions.
- C. The exact ratio of ions in the compound.
- D. The transfer of electrons.
Answer
The correct option is The exact ratio of ions in the compound.. This answer is correct because it matches the approved learning objective to describe the limitations of dot and cross diagrams for giant ionic structures in the subtopic Ionic compounds.
Explanation
The correct option is The exact ratio of ions in the compound.. The exact ratio of ions in the compound. is correct because it directly supports the approved learning objective to describe the limitations of dot and cross diagrams for giant ionic structures. This belongs to the subtopic Ionic compounds within Chemical bonds, ionic, covalent and metallic, 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 Ionic compounds.
Common mistake
Misunderstanding Dot and Cross Diagrams
Students often think that dot and cross diagrams accurately represent the positions of ions in a giant ionic lattice.
Emphasize that dot and cross diagrams show electron transfer but do not depict the three-dimensional arrangement of ions in the lattice.
