OCR GCSE Chemistry — Particles

Master Topic C1 of OCR Gateway Science A GCSE Chemistry (J248): the particle model and the three states of matter, changes of state and heating and cooling curves, the evidence for and limitations of the particle model, the structure of the atom, atomic number, mass number and isotopes, the historical development of the atomic model, electronic structure, and relative atomic mass calculations from isotopic abundance. Worked examples, required-practical and maths skills, exam tips and graded model answers for Foundation and Higher tiers.
