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).
