💡 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
