The exam evaluates foundational chemistry concepts, focusing on atomic structure, bonding, the periodic table, reaction rates, and electrolysis. Key topics include isotopes, group trends, endothermic and exothermic reactions, ionic bonding, and properties of metals and non-metals. Practical applications emphasize calculating relative atomic mass, interpreting reaction profiles, balancing chemical equations, and identifying reaction products in electrolysis. Questions assess understanding of material properties, experimental data interpretation, and the environmental implications of chemical processes. Keywords: GCSE Chemistry, atomic structure, bonding, periodic table, electrolysis, reaction rates, isotopes, reaction profiles, ionic bonding, material properties.
