Feedback and what you get

Questions are marked automatically as pupils answer: a sound and a character reaction show straight away whether they are right, and correct answers earn points, with a results screen at the end. Sentence-writing tasks are for pupils' own answers and are not marked automatically.

From a plum pudding to a tiny nucleus with shells of electrons — see how the model of the atom changed. This 22-slide interactive lesson on electron arrangement takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching Atomic Models and Electron Arrangement in GCSE Chemistry

Pupils follow the development of the atomic model from Dalton and Thomson's plum pudding to Rutherford's nuclear model, Bohr's shells and Chadwick's neutron, and explain what each result of the alpha particle scattering experiment showed. They compare the size of an atom and its nucleus, write electron arrangements for the first 20 elements, link them to group and period, and calculate relative atomic mass from isotope abundances.
