Question
- A. They have a full outer shell of electrons
- B. They readily form compounds
- C. They have low boiling points
- D. They are highly reactive
Answer
The correct option is They have a full outer shell of electrons.
Explanation
The correct option is They have a full outer shell of electrons. They have a full outer shell of electrons 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 b8e341be 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.
