Question
- A. They consist of molecules held together by covalent bonds
- B. They form a giant structure of ions
- C. They are made up of only non-metal atoms
- D. They have low melting points
Answer
The correct option is They form a giant structure of ions. This answer is correct because it matches the approved learning objective to use diagrams to deduce that a compound has an ionic structure in the subtopic Ionic compounds.
Explanation
The correct option is They form a giant structure of ions. They form a giant structure of ions is correct because it directly supports the approved learning objective to use diagrams to deduce that a compound has an ionic structure. 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
Misinterpreting Diagrams
Students often misinterpret diagrams and conclude that a compound has an ionic structure when it actually has a covalent structure.
To fix this, students should carefully analyze the types of atoms involved and the bonding patterns shown in the diagrams, ensuring they recognize the characteristics of ionic versus covalent bonds.
