⚛️ Particles & Structure 3 topics

The Periodic Table

Describe the arrangement of elements in periods and groups; metal/non-metal pattern.

Atomic Structure

State the charges and masses of protons, neutrons and electrons; use atomic number and mass number.

Describe ionic bonding as electron transfer; write ionic formulae.

⚗️ Chemical Reactions 2 topics

Types of Reactions

Classify reactions as synthesis, decomposition, combustion or displacement.

Balancing Equations

Balance symbol equations and use state symbols (s), (l), (g), (aq).

🧪 Acids, Bases & Salts 2 topics
