💡 Exam Tips for Radioactive Decay
🎯 Common Question Types:
- Complete a nuclear decay equation (2–3 marks)
- Compare properties of α, β, γ (3–4 marks)
- Explain why a particular radiation is used for a given purpose (2–3 marks)
- Describe what happens in alpha or beta decay (3 marks)
📝 Key Command Words:
- State: Name the type, give numbers (no explanation needed)
- Describe: Say what happens step by step
- Explain: Give the scientific reason why
- Compare: State at least one similarity and one difference
⚠️ Common Mistakes to Avoid:
- Saying gamma changes the element — it does NOT
- Confusing "most penetrating" with "most dangerous" — context matters
- Forgetting beta particle has atomic number −1 in equations
- Not checking both mass numbers AND atomic numbers balance in equations
