💡 Exam Tips — The Periodic Table
🎯 Common Question Types:
- Use electronic configuration to identify group and period (2 marks)
- Explain why elements in same group have similar properties (3 marks)
- Compare reactivity trends in Group 1 and Group 7 (4 marks)
- Explain why noble gases are unreactive (2 marks)
📝 Key Command Words:
- Explain: Link to outer electrons, not just state the trend
- Compare: Describe both Group 1 and Group 7 trends explicitly
- State: Give the group/period number directly
- Predict: Use the group trend to forecast properties of unknown elements
⚠️ Common Mistakes to Avoid:
- Confusing groups (columns) with periods (rows)
- Saying Group 7 reactivity increases down — it DECREASES
- Forgetting that Group 0 noble gases have FULL outer shells (8, except He which has 2)
- Saying elements are arranged by mass — they are arranged by ATOMIC NUMBER
