GCSE Chemistry Notes: Complete Topic-Wise Breakdown

1. Atomic Structure and the Periodic Table

Key Points:

• Atom = protons + neutrons + electrons

• Atomic number = number of protons

• Mass number = protons + neutrons

Example:
Carbon has atomic number 6 → 6 protons and 6 electrons.

Periodic Table Basics:

• Elements arranged by increasing atomic number

• Groups = similar properties

• Periods = number of electron shells

---

2. Bonding, Structure, and Properties of Matter

Types of Bonding:

Ionic Bonding

• Between metals and non-metals

• Electron transfer

• Strong electrostatic forces

Covalent Bonding

• Between non-metals

• Shared electrons

Metallic Bonding

• Positive metal ions and delocalized electrons

---

3. Quantitative Chemistry Notes

This topic involves calculations.

Important Formulas:

• Moles = mass ÷ relative formula mass

• Concentration = mass ÷ volume

• Percentage yield = (actual ÷ theoretical) × 100

📌 Practice is essential for high marks here.

---

4. Chemical Changes

Reactivity Series:

• Shows how reactive metals are

• More reactive metals displace less reactive ones

Example:
Zinc displaces copper from copper sulfate solution.

Acids, Bases, and Salts:

• Acid + metal → salt + hydrogen

• Acid + base → salt + water

---

5. Energy Changes

Types of Reactions:

• Exothermic: releases heat

• Endothermic: absorbs heat

Key Terms:

• Activation energy

• Reaction profile

• Bond energy

---

6. Rate of Reaction Notes

Factors Affecting Rate:

• Temperature

• Concentration

• Surface area

• Catalysts

Collision Theory:
Reactions occur when particles collide with enough energy.

---

7. Organic Chemistry Notes

Organic chemistry studies carbon compounds.

Key Topics:

• Crude oil and hydrocarbons

• Alkanes and alkenes

• Polymers and plastics

Example:
Ethene is used to make poly(ethene).

---

8. Chemical Analysis

Common Tests:

• Flame tests (metal ions)

• Gas tests (hydrogen, oxygen, carbon dioxide)

• Chromatography

Example:
Carbon dioxide turns limewater milky.
