Examined in Edexcel 1PH0/1 (Paper 1). Edexcel uses context-based scenarios (e.g. "a scientist is studying an isotope of uranium — complete the nuclear symbol") and often includes a calculation alongside a define or describe question. The contamination vs irradiation distinction is tested in risk-benefit contexts on 1PH0/1.
Atomic structure questions appear in nearly every GCSE Physics paper. Common question types include:
- Calculate neutrons from atomic and mass numbers (1 mark — use A − Z)
- Identify isotopes — given data, state which atoms are isotopes and explain why
- Complete nuclear symbols — fill in missing mass or atomic numbers
- Explain why atoms are neutral — equal numbers of protons and electrons
- Compare isotopes — same chemical properties, different physical properties (2–3 marks)
Key command words: "State" (give the number), "Explain" (give the reason with the answer), "Describe" (what you observe or what changes).
