Frequently Examined
Group 7 is one of the most regularly examined topics in GCSE Chemistry. Key question types include: describing the physical properties (colour, state) of halogens (2-3 marks); explaining the reactivity trend in Group 7 (3 marks); writing equations for displacement reactions and describing observations (3-4 marks); and comparing Group 7 with Group 1 reactivity trends (4 marks). Displacement reactions with colour changes are a favourite practical-based question.
