Question
- A. They have a full outer electron shell.
- B. They have a high atomic number.
- C. They are highly reactive.
- D. They have unpaired electrons.
Answer
The correct option is They have a full outer electron shell..
Explanation
The correct option is They have a full outer electron shell.. They have a full outer electron shell. is correct because it directly supports the approved learning objective to explain why noble gases do not easily form molecules. This is tested in the subtopic Group 0 within The periodic table, so the reasoning must stay within AQA GCSE Chemistry 8462 Unit 4.1. The other options are weaker because they either confuse a nearby Chemistry concept, use the wrong subtopic context, or do not answer Group 0 precisely. Repair marker 2b66a5ee keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Noble Gases and Molecular Formation
Students often state that noble gases do not form molecules because they are gases at room temperature.
Emphasize that noble gases do not easily form molecules due to their stable electron arrangements, not their physical state.
