💡 Exam Tips for Ionic Bonding
🎯 Common Question Types:
- Draw dot-cross diagram for NaCl, MgO or MgCl₂ (2-4 marks)
- Explain what ionic bonding is (2-3 marks)
- State the charge on ions of named elements (1 mark each)
- Write the formula of an ionic compound from its ions
📝 Key Command Words:
- State/Name: One-word or short phrase answer
- Explain: Give the mechanism — transfer, ions form, electrostatic attraction
- Draw: Dot-cross diagram with brackets and charges
- Compare: State both ionic AND covalent features side by side
⚠️ Common Mistakes to Avoid:
- Saying electrons are "shared" in ionic bonding — they are TRANSFERRED
- Forgetting square brackets and charges on dot-cross diagrams
- Saying "the bond is the electrons" — the bond IS the electrostatic attraction
- Showing inner electron shells in dot-cross diagrams — outer shell only!
- Getting charges wrong: remember metals are positive, non-metals are negative
