🎯 Exam Focus
Frequently Examined
Examined in Edexcel 1PH0/1 (Paper 1). Fission and fusion are higher tier topics on Edexcel 1PH0. Edexcel extended-answer questions (6 marks) on nuclear power vs fossil fuels require students to evaluate both sides and reach a conclusion — not just list facts. Binding energy and mass-energy equivalence (E = mc²) appear at higher tier. Nuclear equations for fission (balancing both sides) are regularly tested.
Fission and fusion are high-value topics, especially for extended-answer questions:
- Describe nuclear fission including chain reaction (3–4 marks)
- Explain the role of moderator and control rods (2 marks each)
- Compare fission and fusion in a table or description (4 marks)
- Explain why fusion is difficult on Earth (3 marks)
- Evaluate nuclear power vs fossil fuels — extended answer (6 marks)
