The Cambridge IGCSE Chemistry 0620 syllabus provides a comprehensive foundation in chemistry for students aged 14–16, covering both theoretical and practical aspects.

Key aims include developing scientific knowledge, experimental skills, safe laboratory practices, and the ability to analyze and communicate scientific information effectively.

Major topics covered are:

• States of matter

• Atoms, elements, and compounds

• Stoichiometry

• Electrochemistry

• Chemical energetics

• Chemical reactions

• Acids, bases, and salts

• The Periodic Table

• Metals

• Chemistry of the environment

• Organic chemistry

• Experimental techniques and chemical analysis

Assessment is divided into Core and Extended levels, with multiple-choice, theory, and practical components. Core covers foundational content, while Extended includes additional material for higher achievement.

Assessment objectives are:

• Knowledge with understanding (50%)

• Handling information and problem-solving (30%)

• Experimental skills and investigations (20%)

Students are expected to:

• Understand scientific phenomena, laws, and theories

• Apply knowledge to new situations and solve problems

• Develop and evaluate experimental methods

• Interpret and present data, including use of scientific vocabulary and conventions

Key concepts include:

• Atomic structure: nucleus, protons, neutrons, electrons, isotopes, and electron configuration

• Chemical bonding: ionic, covalent, and metallic bonds, and their properties

• States of matter and changes of state, explained by kinetic particle theory

• Periodic Table: trends, group properties, and electron arrangements

• Stoichiometry: calculations involving relative atomic and molecular masses, moles, and chemical equations

Sample equations in MathML:

• Relative atomic mass: Arelement = ∑(isotope ext{ }mass × abundance)∑(abundance)

• General chemical equation: aA + bB → cC + dD

The syllabus emphasizes the development of transferable skills such as problem-solving, critical thinking, and the application of scientific knowledge to real-world contexts.
