🎯 Exam Focus
Frequently Examined
Ionic compound properties are examined very frequently. Key question patterns:
- Explain the high melting point of an ionic compound — always reference "many strong electrostatic forces" and "large amount of energy needed" (2-3 marks)
- Explain conductivity — distinguish between solid (no conduction, fixed ions) and molten/dissolved (conducts, free ions) — 2 marks
- Compare two ionic compounds — which has higher melting point and why (ion charges and size) — 2-3 marks
- Brittleness — explain in terms of layer displacement and repulsion — 2 marks
The critical phrase examiners want to see is: "ions are free to move and carry charge" for conductivity questions.
