40 exam-style questions on AQA GCSE Physics 4.1 Atoms and isotopes, covering 4.1.1 The structure of an atom, 4.1.2 Mass number, atomic number and isotopes, and 4.1.3 The development of the model of the atom (common content with chemistry). Each one has a worked solution and a mark scheme showing where the marks go.
