GCSE Physics: Atomic Structure & Radioactivity — Revision Workbook

GCSE Physics: Atomic Structure & Radioactivity is a focused revision workbook mapped to AQA GCSE Physics Topic 4 (specification 6.4). Across four auto-marked tasks and one extended six-mark question, learners revise the structure of the atom — a nucleus of protons and neutrons with electrons in shells — and the vast difference in size between the atom (about 1×10⁻¹⁰ m) and its nucleus (about 1×10⁻¹⁴ m); the development of the atomic model from the plum-pudding model to Rutherford’s nuclear model and Bohr’s energy levels; isotopes; the three types of nuclear radiation (alpha, beta and gamma), their penetration through paper, aluminium and lead and their ionising power; radioactive decay and activity in becquerel; nuclear equations and the mass-number and atomic-number changes in alpha and beta decay; half-life calculations, including the activity left after several half-lives and finding a half-life from data; and the difference between contamination and irradiation, with the uses and dangers of radiation. Every question is auto-marked on screen, or the whole book can be printed with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
