Question
- A. Reactivity increases
- B. Reactivity decreases
- C. Reactivity remains the same
- D. Reactivity fluctuates
Answer
The correct option is Reactivity increases.
Explanation
The correct option is Reactivity increases. Reactivity increases is correct because it directly supports the approved learning objective to describe and explain why reactivity increases down Group 1. This is tested in the subtopic Group 1 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 1 precisely. Repair marker fea7156d keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Reactivity Misunderstanding
Students often believe that reactivity increases down Group 1 because the elements become heavier.
Reactivity increases down Group 1 due to the increasing distance of the outer electron from the nucleus, which makes it easier to lose that electron.
