Question
- A. Attraction between oppositely charged ions
- B. Sharing of pairs of electrons between atoms
- C. Attraction between metal atoms and delocalised electrons
- D. Transfer of electrons from one atom to another
Answer
The correct option is Sharing of pairs of electrons between atoms. This answer is correct because it matches the approved learning objective to represent single covalent bonds in small molecules using lines in the subtopic Covalent bonding.
Explanation
The correct option is Sharing of pairs of electrons between atoms. Sharing of pairs of electrons between atoms is correct because it directly supports the approved learning objective to represent single covalent bonds in small molecules using lines. This belongs to the subtopic Covalent 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 Covalent bonding.
Common mistake
Misunderstanding Bond Representation
Students often confuse the representation of single covalent bonds in small molecules by using dots instead of lines.
To fix this, remember that single covalent bonds should be represented using lines, as this indicates the sharing of pairs of electrons between atoms.
