💡 Exam Tips for Atomic Structure
🎯 Common Question Types:
- Calculate number of neutrons from A and Z (1 mark)
- Explain why atoms have no overall charge (2 marks)
- Identify and explain isotopes from data (2–3 marks)
- Describe similarities and differences between isotopes (3 marks)
📝 Key Command Words:
- State: Give the value or name without explanation
- Calculate: Show working and give the answer with units
- Explain: Give the reason — "because..." or "since..."
- Compare: Give both a similarity AND a difference
⚠️ Common Mistakes to Avoid:
- Confusing mass number and atomic number — Z is always the smaller number
- Forgetting that neutral atoms have protons = electrons
- Saying isotopes have "different chemical properties" — they don't!
- Writing mass number as a decimal — it must be a whole number
