The syllabus covers fundamental concepts in chemistry, including states of matter, atomic structure, stoichiometry, electrochemistry, energetics, chemical reactions, acids and bases, the Periodic Table, metals, environmental chemistry, organic chemistry, and experimental techniques.

Key aims are to develop scientific knowledge, experimental skills, safe laboratory practices, and the ability to use scientific data and communicate effectively using scientific terminology and conventions.

Assessment is divided into Core and Extended levels, with multiple-choice, theory, and practical components. Core and Extended candidates take different combinations of papers, with practical assessment options including a practical test or an alternative to practical paper.

Assessment objectives include:

• Knowledge with understanding (50%)

• Handling information and problem-solving (30%)

• Experimental skills and investigations (20%)

Core topics include:

• States of matter: properties and changes of solids, liquids, and gases; effects of temperature and pressure on gases.

• Atomic structure: nucleus, protons, neutrons, electrons, electron configuration, and the Periodic Table.

• Isotopes: definition, examples, and calculation of relative atomic mass.

• Chemical bonding: ionic and covalent bonds, properties of ionic and covalent compounds, and metallic bonding.

• Giant covalent structures: properties and uses of graphite and diamond.

Students are expected to:

• Apply knowledge to unfamiliar contexts and solve quantitative and qualitative problems.

• Plan and carry out experiments, make and interpret observations, and evaluate methods and results.

• Understand the impact of chemistry on society and the environment.

Equations and calculations are integral, such as:

• Relative atomic mass: Arelement=∑isotope×abundancetotal abundance

• Gas laws and stoichiometric calculations are also included.

The syllabus emphasizes the development of transferable skills such as problem-solving, critical thinking, and the application of scientific methods.
