Question
- A. They increase
- B. They decrease
- C. They remain constant
- D. They vary unpredictably
Answer
The correct option is They increase.
Explanation
The correct option is They increase. They increase is correct because it directly supports the approved learning objective to predict properties of Group 7 elements from trends down the group. 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 7838afd0 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Reactivity Trends
Students often think that reactivity increases down Group 7 instead of decreases.
Remember that as you move down Group 7, the outer electrons are further from the nucleus, making it harder for the atom to attract electrons and thus decreasing reactivity.
