🎯 Exam Focus
Frequently Examined
Covalent bonding questions appear on every paper. Key patterns:
- Draw a dot-cross diagram for H₂, H₂O, NH₃, CH₄, HCl, Cl₂, O₂, N₂, CO₂ — 2-3 marks
- Explain why a substance is covalent (non-metals, electrons shared) — 2 marks
- State the number of bonds an atom makes (from electron configuration) — 1 mark
- Compare single/double/triple bonds in terms of strength and length — 2 marks
- Higher tier: Explain why N₂ is unreactive (triple bond, high bond energy) — 2 marks
Common exam trap: distinguishing between properties of simple molecular covalent substances vs giant covalent structures.
