Question
- A. It involves the sharing of electron pairs between atoms.
- B. It is the electrostatic attraction between oppositely charged ions.
- C. It is the strong attraction between metal atoms and delocalised electrons.
- D. It occurs only in non-metallic elements.
Answer
The correct option is It is the strong attraction between metal atoms and delocalised electrons.. This answer is correct because it matches the approved learning objective to explain that outer-shell electrons in metals are delocalised in the subtopic Metallic bonding.
Explanation
The correct option is It is the strong attraction between metal atoms and delocalised electrons.. It is the strong attraction between metal atoms and delocalised electrons. is correct because it directly supports the approved learning objective to explain that outer-shell electrons in metals are delocalised. This belongs to the subtopic Metallic 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 Metallic bonding.
Common mistake
Misunderstanding Delocalised Electrons
Students often think that outer-shell electrons in metals are localized and not free to move.
Emphasize that outer-shell electrons in metals are delocalised, meaning they can move freely throughout the metallic structure, contributing to properties like conductivity.
