Includes short- and extended-response tasks on elements versus compounds, interpreting chemical formulas, balanced symbol equations with state symbols, mixtures and separation techniques such as distillation, and separating immiscible components. Also addresses atomic history (Thomson, Rutherford, Bohr), plus calculations of protons, neutrons and electrons, overall charge, ion formation, and comparisons of atomic structures.","GraspIT – AQA GCSE Atomic Structure & the Periodic Table  \nA .
