JAMB Chemistry Notes
Lesson notes for 10 JAMB Chemistry topics, each with worked examples and the key terms to know. Free to read, no account needed.
- Atomic Structure and Chemical BondingHow atoms are built, how electrons arrange themselves in shells, and how ionic and covalent bonds form.
- Acids, Bases, and SaltsThe pH scale, neutralization reactions, how salts are prepared, and how indicators show whether a substance is acidic or basic.
- Organic ChemistryHydrocarbons, homologous series, functional groups, and the naming rules behind alkanes and alkenes.
- Chemistry of Non-metals and GasesHow common laboratory gases are prepared and identified, and general trends in non-metal chemistry.
- Physical ChemistryWhat speeds up or slows down a reaction, how equilibrium responds to change, and the difference between exothermic and endothermic reactions.
- Periodicity and Inorganic ChemistryHow the periodic table is organized, and the trends in atomic size, ionization energy, and reactivity across periods and down groups.
- Electrochemistry and Redox ReactionsOxidation and reduction, assigning oxidation numbers, and how electrolysis uses electricity to drive a chemical reaction.
- Environmental and Industrial ChemistryAir and water pollution, the greenhouse effect, and two major industrial processes: the Haber process and the Contact process.
- Chemistry of MetalsThe reactivity series, how metals are extracted based on their reactivity, and why metals corrode.
- Quantitative ChemistryThe mole concept, empirical and molecular formulas, and calculations from balanced chemical equations.
