MYP Chemistry (Years 4–5) Study Notes
A complete, conceptually ordered roadmap for mastering MYP Chemistry. Topics progress logically — from the nature of matter to modern applications.
Topic 1: Matter and the Particle Model
Topic 2: Pure Substances, Mixtures, and Separation
Topic 3: Atomic Structure and the Periodic Table
Topic 4: Chemical Bonding and Structure
Topic 5: Chemical Reactions and Conservation of Mass
Topic 6: Quantitative Chemistry and Stoichiometry
Topic 7: Energy Changes and Rates of Reaction
Topic 8: Acids, Bases, and Salts
Topic 9: Metals, Reactivity, and Extraction
Topic 10: Organic Chemistry and Carbon Compounds
Topic 11: Environmental and Atmospheric Chemistry
Topic 12: Nuclear Chemistry and Radioactivity
This progression ensures that each topic builds conceptually upon the previous one — guiding students from foundational particle understanding to complex applied chemistry.
