Question
- A. Atoms lose electrons to form positive ions
- B. Atoms gain electrons to form negative ions
- C. Atoms share pairs of electrons to form molecules
- D. Atoms do not interact with each other
Answer
The correct option is Atoms share pairs of electrons to form molecules. This answer is correct because it matches the approved learning objective to describe chemical reactions in terms of proton transfer, electron transfer or electron sharing in the subtopic Universal chemistry ideas.
Explanation
The correct option is Atoms share pairs of electrons to form molecules. Atoms share pairs of electrons to form molecules is correct because it directly supports the approved learning objective to describe chemical reactions in terms of proton transfer, electron transfer or electron sharing. This belongs to the subtopic Universal chemistry ideas within Key ideas in chemistry, 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 Universal chemistry ideas.
Common mistake
Confusing Types of Bonding
Students often confuse electron transfer (ionic bonding) with electron sharing (covalent bonding) when describing chemical reactions.
To fix this, clearly differentiate between ionic and covalent bonding: ionic bonding involves the transfer of electrons, while covalent bonding involves the sharing of electrons.
