💡 Exam Tips — Electronic Configuration
🎯 Common Question Types:
- Write or draw the electronic configuration of a given element (2 marks)
- Use configuration to identify group and period (2 marks)
- Explain why elements in the same group have similar properties (2-3 marks)
- Explain why noble gases are unreactive (2 marks)
📝 Key Command Words:
- Write: Give the configuration as numbers, e.g., 2,8,1
- Draw: Show circles for shells with dots/crosses for electrons
- Explain: Mention outer electrons and their role in bonding
- State: Give the group or period number directly
⚠️ Common Mistakes to Avoid:
- Putting more than 2 electrons in the 1st shell
- Putting more than 8 in the 2nd or 3rd shells
- Confusing group number (outer electrons) with period number (shells)
- Forgetting that noble gases have FULL outer shells — that is why they are unreactive
