Question
- A. It occurs only in non-metals.
- B. It involves the sharing of electrons between non-metal atoms.
- C. It involves delocalised electrons that allow metals to conduct electricity.
- D. It is characterized by strong covalent bonds.
Answer
The correct option is It involves delocalised electrons that allow metals to conduct electricity.. This answer is correct because it matches the approved learning objective to identify metallic bonding as attraction involving metal atoms and delocalised electrons in the subtopic Chemical bonds.
Explanation
The correct option is It involves delocalised electrons that allow metals to conduct electricity.. It involves delocalised electrons that allow metals to conduct electricity. is correct because it directly supports the approved learning objective to identify metallic bonding as attraction involving metal atoms and delocalised electrons. This belongs to the subtopic Chemical bonds 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 Chemical bonds.
Common mistake
Confusing Metallic Bonding
Students often confuse metallic bonding with ionic bonding, thinking that it involves the transfer of electrons between atoms.
Remember that metallic bonding involves the attraction between positive metal ions and delocalised electrons, not the transfer of electrons like in ionic bonding.
