Question
- A. They have a full outer electron shell
- B. They have a high atomic mass
- C. They are all gases at room temperature
- D. They are non-metals
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 are unreactive in terms of stable electron arrangements. 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 9ac35def keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Noble Gas Reactivity
Students often state that noble gases are unreactive because they have full outer shells, but they do not explain this in terms of stable electron arrangements.
Students should clarify that noble gases have stable electron arrangements due to having complete outer electron shells, which prevents them from reacting with other elements.
