IGCSE CHEMISTRY 
ATOMS
C1 THE PARTICULATE NATURE OF MATTER (AND C3.3 ATOMIC STRUCTURE)

Before you start you can look back at 7G Solids, liquids and Gases, 7H Solutions or 8EF Elements, Mixtures and Compounds.

If you only remember one thing...

ATOMS HAVE PROTONS (+) AND NEUTRONS (O) IN THEIR NUCLEUS AND THE ELECTRONS (-) FLY AROUND IN SHELLS.

This is the first of the 14 Chemistry units:
Atoms (C1-3)
Compounds (C1-3)
Mixtures (C2,3)
C4. Stoichiometry
C5. Electricity and Chemistry 
C6. Energy Changes in Chemical Reactions
C7. Chemical Reactions
C8. Acids, Bases and Salts
C9. The Periodic Table
C10. Metals
C11. Air and Water 
C12. Sulphur 
C13. Carbonates 
C14. Organic Chemistry

C1,2,3 COMPOUNDS
C2,3 MIXTURES
