Each chapter can be downloaded as a PDF in Urdu or English medium, with exercise notes alongside. They follow the new Punjab Curriculum and Textbook Board (PCTB) book for 2026-27 and suit Lahore, Rawalpindi, Multan, Gujranwala, Faisalabad, Sargodha, Bahawalpur, DG Khan and Sahiwal boards.

9th Class Chemistry Notes 2026 – Punjab Board (Urdu & English Medium)

Chemistry in 9th class stops being about memorising a list. The new book asks you to explain why things happen: why a gas fills a container, why sodium gives up an electron so easily, why vinegar turns litmus red. Good notes should help with that, and this page is built for it.

Pick your chapter below, choose your medium, and download the PDF. Nothing to sign up for. If you need help finding your chapter, the guide under the table explains what each one covers.

What each chapter covers

Chapter 1 notes: States of Matter and Phase Changes

Solids, liquids and gases explained through particle behaviour, and what happens when a substance melts, boils or condenses. It's a good first chapter to revise because later ones lean on the same idea.

Chapter 2 notes: Atomic Structure

Protons, neutrons and electrons, how electrons are arranged, and why isotopes of one element behave the same way chemically. Practise writing electronic configurations by hand.

Chapter 3 notes: Chemical Bonding

How atoms join: ionic, covalent and metallic bonding, and how each type shapes properties such as melting point and conductivity. Dot-and-cross diagrams are usually where marks are won or lost.

Chapter 4 notes: Stoichiometry

Moles, molar mass and balanced equations, then the calculations that follow. It's the most numerical chapter in the first half. Work through the exercise notes rather than just reading them.

Chapter 5 notes: Energetics

Heat changes in reactions, including exothermic and endothermic processes and how energy diagrams show them.

Chapter 6 notes: Equilibria

Reversible reactions and the idea of a balance that keeps moving. Short definitions matter here.

Chapter 7 notes: Acid Base Chemistry

Properties of acids and bases, the pH scale, neutralisation and salts. Students search for this chapter more than most, so both English and Urdu notes are linked above.

Chapters 8 to 13

The Periodic Table and periodic trends (8), group properties of common element families (9), pollution and the environment (10), an introduction to hydrocarbons (11), then data handling (12) and safe practical work (13). Chapters 12 and 13 are skill-based, so treat them as practice, not memorisation.

How to use these notes

Read the chapter in the textbook first, then use the notes to tighten it. Definitions and short answers are quickest to revise from notes. Diagrams, calculations and equations need pen and paper. Solve the exercise notes only after you've tried the questions yourself.
