This exam tips covers Exam Tips — The Periodic Table within The Periodic Table for GCSE Chemistry. Revise The Periodic Table in Atomic Structure for GCSE Chemistry with 22 exam-style questions and 24 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 12 of 13 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.
💡 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
Practice questions for The Periodic Table
How are elements arranged in the modern periodic table?
Mendeleev's periodic table was eventually accepted by other scientists. Explain why scientists were convinced that his table was correct.
Quick recall flashcards
What are the Group 1 elements called?
Alkali metals (Li, Na, K, Rb, Cs, Fr)
Where are non-metals found?
On the right side of the periodic table
