Question
- A. The shared pairs of electrons
- B. The individual atoms involved
- C. The ionic charges of the atoms
- D. The bonds formed between atoms
Answer
The correct option is The ionic charges of the atoms. This answer is correct because it matches the approved learning objective to draw dot and cross diagrams for hydrogen, chlorine, oxygen, nitrogen, hydrogen chloride, water, ammonia and methane in the subtopic Covalent bonding.
Explanation
The correct option is The ionic charges of the atoms. The ionic charges of the atoms is correct because it directly supports the approved learning objective to draw dot and cross diagrams for hydrogen, chlorine, oxygen, nitrogen, hydrogen chloride, water, ammonia and methane. 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
Common Mistake in Dot and Cross Diagrams
Students often confuse the representation of shared electrons in dot and cross diagrams, incorrectly showing them as separate rather than shared between atoms.
Emphasize that in dot and cross diagrams, shared pairs of electrons should be represented clearly between the two atoms involved, indicating that they are being shared.
