Question
- A. Reactivity decreases
- B. Reactivity increases
- C. Reactivity remains the same
- D. Reactivity fluctuates
Answer
The correct option is Reactivity decreases.
Explanation
The correct option is Reactivity decreases. Reactivity decreases is correct because it directly supports the approved learning objective to describe and explain why reactivity decreases down Group 7. This is tested in the subtopic Group 7 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 7 precisely. Repair marker dd0feadd keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Reactivity Misunderstanding
Students often think that reactivity increases down Group 7 instead of decreases.
Focus on the concept that as you move down Group 7, the outer electrons are further from the nucleus, making it harder for the atom to attract additional electrons, thus decreasing reactivity.
