💡 Exam Tips — Atomic Structure
🎯 Common Question Types:
- Calculate protons, electrons, neutrons from atomic/mass numbers (2 marks)
- Describe the development of the atomic model over time (4-6 marks)
- Define isotopes and explain why they have similar chemical properties (3 marks)
- Compare subatomic particles by mass and charge (table completion, 3 marks)
📝 Key Command Words:
- State: Give the value with no working needed
- Calculate: Show neutrons = mass − atomic number
- Explain: Give the reason, not just the fact
- Describe: Account for what happened in Rutherford's experiment
⚠️ Common Mistakes to Avoid:
- Confusing atomic number and mass number — atomic number is SMALLER
- Forgetting that electrons have negligible mass
- Saying isotopes have different protons — they have different NEUTRONS
- Thinking the atom is mostly solid — it is mostly empty space
