About this Simulation

This interactive simulation enables learners to explore and compare Rutherford's and Thomson's competing models of atomic structure. Students can visualize electron behavior, observe nuclear positioning, and understand how experimental evidence shaped our conception of the atom through dynamic, adjustable parameters.

Learning objectives: Understand the key differences between Thomson's plum-pudding and Rutherford's nuclear atomic models | Explore how electrons and nuclei are positioned according to each model | Interpret experimental evidence that led to atomic model development
