💡 Exam Tips for Metallic Bonding
🎯 Common Question Types:
- Explain how metals conduct electricity (2 marks)
- Explain why metals are malleable and ductile (2 marks)
- Compare electrical conductivity of metals vs ionic compounds (2-3 marks)
- Predict which of two metals has higher melting point and explain why (2 marks)
📝 Key Command Words:
- Explain: Reference "delocalised electrons free to move" for conductivity
- Explain: Reference "layers of ions slide, electron sea maintains bond" for malleability
- Compare: State the key difference — metals conduct as solids, ionic compounds do not
- Predict: Apply the rules about charge and electron numbers to predict relative MP
⚠️ Common Mistakes to Avoid:
- Saying "free ions" conduct in metals — it's FREE ELECTRONS, not ions
- Saying "metallic bonds break" when a metal deforms — the bond does NOT break, ions slide within the electron sea
- Confusing metallic bonding with covalent bonding — metallic has a sea of electrons, covalent has specific shared pairs
- Not using the word "delocalised" — this is the key exam term for metallic bonding
