💡 Exam Tips — Noble Gases
🎯 Common Question Types:
- Explain why noble gases are unreactive (2 marks)
- Give a use of helium/argon/neon and explain why that gas is chosen (2 marks)
- Compare the reactivity of noble gases with Group 1 or Group 7 (3 marks)
- State the electronic configuration of helium and explain its stability (2 marks)
📝 Key Command Words:
- Explain: Link to full outer shell — no need to gain, lose, or share electrons
- State: Give the property (unreactive, monatomic, non-flammable)
- Give a reason: Always link use to the unreactive nature
- Compare: Contrast full outer shell (stable) with incomplete shell (reactive)
⚠️ Common Mistakes to Avoid:
- Saying helium has 8 outer electrons — it only has 2 (full 1st shell)
- Calling noble gases "inert gases" — the preferred term is "noble gases"
- Forgetting to link uses to the unreactive nature
- Saying noble gases have no electrons — they just have full outer shells
