Complete topic map
Every topic recorded for this subject in the curriculum is reproduced below in its full hierarchy. The descriptions reflect the mapped scope without implying additional exam rules.
Development of the periodic table and atomic models, atomic structure, radioactivity, electronic configuration of atoms, and oxidation and reduction concepts.
How atoms combine through ionic and covalent bonding, electronegativity, intermolecular forces, and the prediction of molecular shapes.
States of matter and the gas laws, the mole concept, determining chemical formulas, and quantitative calculations from balanced chemical equations.
Expressing concentration of solutions, the theory of acids and bases, and carrying out titrations to determine unknown concentrations quantitatively.
Sources and structure of hydrocarbons including aliphatic and aromatic compounds, oil refining, exothermic and endothermic reactions, and heats of reaction.
The factors that affect how fast chemical reactions proceed, including concentration, temperature, surface area and catalysts, and reaction-rate theory.
Structure and bonding of carbon compounds, families of organic compounds, characteristic reactions and mechanisms, and key organic chemical reactions including polymerisation.
Reversible reactions and dynamic equilibrium, the equilibrium constant, and how systems respond to changes in conditions (Le Chatelier's principle).
The chemistry of water, including hardness, water treatment, water-quality parameters such as pH and dissolved oxygen, and instrumental analysis of water.
An optional study extending the core through general principles of the chemical industry and a case study of a specific Irish-based chemical manufacturing process.
An optional study of the chemistry of the atmosphere, covering oxygen, nitrogen and carbon compounds, ozone, and atmospheric pollution and its effects.
An optional study of the structure and properties of materials such as crystals, metals, semiconductors, and the chemistry underlying their uses.
An optional study of the electrochemical series, electrolysis, corrosion of metals, and the chemical principles used to extract metals from their ores.
