Cambridge Periodic Table: Official Syllabus Guide

Cambridge Exam Definition:

"The Periodic Table is a systematic arrangement of elements in order of increasing atomic number, showing the periodic repetition of chemical and physical properties."

The Cambridge Periodic Table follows the international IUPAC system but focuses specifically on elements and trends examined in O Level (5070) and IGCSE (0620) Chemistry exams.

Essential Foundation Concepts:

Before mastering the Periodic Table, ensure you understand: Atomic Structure, Electronic Configuration, and Chemical Bonding Principles.

Periodic Table Structure: Cambridge Requirements

Component	Cambridge Focus	Exam Importance
Periods (Rows)	7 horizontal periods - know elements of Periods 1-3 thoroughly	High - Direct questions on period trends
Groups (Columns)	Groups 1, 2, 7, 0 - Alkali metals to Noble gases	Very High - Group properties frequent in papers
Metals/Non-metals	Division at stepped line - know metal/non-metal properties	High - Classification questions common
Transition Metals	Middle block - know basic properties	Medium - Usually 1-2 questions per paper

Key Periodic Trends - Cambridge Exam Focus

📈 Atomic Radius Trend

Decreases across a period (increased nuclear pull)

Increases down a group (more electron shells)

Exam Tip: Always explain trends using nuclear charge and electron shells

⚡ Ionization Energy Trend

Increases across a period (harder to remove electrons)

Decreases down a group (easier to remove outer electrons)

Exam Tip: Link to reactivity of Groups 1 & 2

🧲 Electronegativity Trend

Increases across a period (stronger electron attraction)

Decreases down a group (weaker attraction to nucleus)

Exam Tip: Fluorine is most electronegative (4.0)

Chemistry Cheat Sheet: Ion Identification & Tests

Groups & Families - Must-Know Properties

Group 1 - Alkali Metals

Elements: Li, Na, K, Rb, Cs, Fr
Reactivity: Increases down the group
Reaction with Water: Metal + Water → Metal hydroxide + Hydrogen
Exam Focus: Know reaction trends and safety precautions

Group 7 - Halogens

Elements: F, Cl, Br, I, At
Reactivity: Decreases down the group
Displacement Reactions: More reactive halogens displace less reactive ones
Exam Focus: Displacement experiments and color changes

Group 0 - Noble Gases

Elements: He, Ne, Ar, Kr, Xe, Rn
Properties: Monatomic, colorless, unreactive
Uses: Inert atmospheres, lighting, balloons
Exam Focus: Explain unreactivity using electronic configuration

🎯 Pattern Recognition

• Group number = Number of valence electrons

• Period number = Number of electron shells

• Metals on left, non-metals on right

📝 Practice Strategies

• Draw blank tables and fill from memory

• Focus on Groups 1, 2, 7, 0 and Periods 2-3

• Use flashcards for element symbols

Cambridge Exam Success Strategies

✅ Trend Explanation Framework

When explaining periodic trends, always mention:

Nuclear charge (proton number)
Distance from nucleus
Shielding effect of inner electrons

⚠️ Common Mistakes to Avoid

Confusing period trends with group trends
Forgetting that noble gases have full outer shells
Mixing up metal/non-metal properties
Incorrectly stating reactivity trends
