9. Metals – Properties, extraction, and uses of metals

10. Chemistry of the Environment – Environmental chemistry and pollution

11. Organic Chemistry – Introduction to carbon compounds and their reactions

12. Experimental Techniques and Chemical Analysis – Laboratory methods and analytical techniques

5. Assessment Overview

The assessment structure is designed to evaluate both theoretical knowledge and practical skills. There are two main routes: Core and Extended, with an additional practical component.

• Core Assessment: For students aiming for grades C to G

• Extended Assessment: For students aiming for grades A* to G (includes Core and Supplement content)

• Practical Assessment: All candidates take one practical paper

Core Assessment Papers

• Paper 1: Multiple Choice (Core) – 40 marks, 45 minutes, 30% of total grade

• Paper 3: Theory (Core) – 80 marks, 1 hour 15 minutes, 50% of total grade

Extended Assessment Papers

• Paper 2: Multiple Choice (Extended) – 40 marks, 45 minutes, 30% of total grade

• Paper 4: Theory (Extended) – 80 marks, 1 hour 15 minutes, 50% of total grade

Practical Assessment Papers

• Paper 5: Practical Test – 1 hour 15 minutes, 40 marks, 20% of total grade

• Paper 6: Alternative to Practical – 1 hour, 40 marks, 20% of total grade

All assessments are externally marked and test both knowledge and application of chemistry concepts.

6. Skills Developed

Through the study of this syllabus, students will develop:

• Scientific Knowledge: Understanding of key chemical concepts and processes

• Experimental Skills: Planning, conducting, and analyzing experiments

• Data Analysis: Interpreting and presenting scientific data

• Communication: Using scientific language and conventions accurately

• Problem-Solving: Applying knowledge to new situations and real-world problems

7. Example: The Mole Concept (from Stoichiometry)

The mole is a fundamental concept in chemistry used to count particles such as atoms, molecules, or ions.

• Definition: One mole contains particles (Avogadro's number).

• Formula: Number of moles =

• Application: Used in chemical equations to relate masses of reactants and products.
