Question
- A. Reactivity increases down the group
- B. Reactivity decreases down the group
- C. Reactivity remains constant down the group
- D. Reactivity varies randomly down the group
Answer
The correct option is Reactivity increases down the group.
Explanation
The correct option is Reactivity increases down the group. Reactivity increases down the group is correct because it directly supports the approved learning objective to predict properties of Group 1 elements from trends down the group. 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 064cceda keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Reactivity Trends
Students often think that all Group 1 elements react with water in the same way, without considering their increasing reactivity down the group.
Emphasize the trend that reactivity increases down Group 1, leading to more vigorous reactions with water for elements like potassium compared to lithium.
