Atomic Models and Their Development

Start with a mind map

Atomic Models and Their Development is a section of the Atomic Structure unit in Physics. Its resources offer several ways to study the development of the atomic model. Start with the mind map Discovery of the Atom, which introduces John Dalton and his atomic theory. Use it to make a short list of the ideas you want to explore further.

Next, open P4 Atomic structure. It covers models of the atom and introduces J J Thomson's plum pudding model. Compare the ideas in the two maps and note any questions you want to return to.

Explore Rutherford's experiment

The flashcard deck Rutherford's experiment asks about the procedure, results and conclusions of the experiment. Try answering each question before checking the card. If you want another view, the mind map E. Rutherford's Gold Film Experiment describes the experiment using a beam of alpha particles and a thin metal foil.

You can also use Physics P2B - The Atom to look at Rutherford scattering and the move away from the plum pudding model. Return to the earlier map to compare what each resource says.

Practice and connect your study

After using the maps and flashcards, try Atomic Timeline quiz. Use it as a chance to practice, then return to the maps to check anything you want to study again. Teachers can also choose a map and a set of flashcards to support work on the topic.

As part of Atomic Structure, this topic brings together resources on the atom and how its model developed. Choose a mind map, work through a flashcard deck, and then try a quiz.
