- A. Boiling points increase down the group
- B. Boiling points decrease down the group
- C. Boiling points remain the same down the group
- D. Boiling points are unpredictable down the group
Answer
The correct option is Boiling points increase down the group.
Explanation
The correct option is Boiling points increase down the group. Boiling points increase down the group is correct because it directly supports the approved learning objective to describe the trends in melting point and boiling point 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 d9c5dfc0 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Melting and Boiling Points Confusion
Students often confuse the trends in melting point and boiling point down Group 7, thinking both increase instead of recognizing that melting points increase while boiling points also increase but at a different rate.
To fix this, students should create a table comparing the melting and boiling points of Group 7 elements, noting the specific values and trends to visualize how each property changes down the group.
