How bonding and structure are related to the properties of substances
Question
- A. It makes them highly reactive.
- B. It allows them to conduct electricity.
- C. It prevents them from being shaped.
- D. It gives them low melting points.
Answer
The correct option is It allows them to conduct electricity.. This answer is correct because it matches the approved learning objective to describe pure metals as atoms arranged in regular layers in the subtopic Properties of metals and alloys.
Explanation
The correct option is It allows them to conduct electricity.. It allows them to conduct electricity. is correct because it directly supports the approved learning objective to describe pure metals as atoms arranged in regular layers. This belongs to the subtopic Properties of metals and alloys 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 metals and alloys.
Common mistake
Misunderstanding Metal Structure
Students often describe pure metals as having random arrangements of atoms instead of regular layers.
Emphasize that pure metals have atoms arranged in regular layers, which allows them to slide over each other.
