Question
- A. A giant structure of oppositely charged ions.
- B. A small group of covalently bonded atoms.
- C. A mixture of metals and non-metals.
- D. A compound with shared electron pairs.
Answer
The correct option is A giant structure of oppositely charged ions.. This answer is correct because it matches the approved learning objective to explain why the charge on a simple ion is linked to electron loss or electron gain in the subtopic Ionic bonding.
Explanation
The correct option is A giant structure of oppositely charged ions.. A giant structure of oppositely charged ions. is correct because it directly supports the approved learning objective to explain why the charge on a simple ion is linked to electron loss or electron gain. This belongs to the subtopic Ionic bonding 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 bonding.
Common mistake
Misunderstanding Ion Charges
Students often confuse the charge of a simple ion with the number of electrons lost or gained, thinking that the charge is simply the number of electrons involved.
Emphasize that the charge on a simple ion is determined by the loss of electrons for positive ions and the gain of electrons for negative ions, and that it reflects the difference between protons and electrons.
