Simulation of Nuclear decay Simulation Overview Three tabs show alpha, beta, and gamma nuclear decay at the atomic level. Each opens with an unstable nucleus — protons (red) and neutrons (blue) packed together and shaking furiously inside a glowing boundary ring, surrounded by four bright electron shells. At the moment of decay the nucleus instantly […]

Simulation of Chadwick’s Neutron discovery Suggested class activity — “What does the data tell us?” Let me check our past conversations for any relevant context first. Chadwick’s Neutron Discovery — Simulation Description The simulation recreates James Chadwick’s 1932 experiment that proved the existence of the neutron. It runs left to right across three stages: A

Simulation of Alpha particle scattering experiment What the simulation shows An interactive recreation of the 1909 Geiger–Marsden gold foil experiment. Alpha particles are fired from the left toward a gold atom. A dashed circle shows the atom boundary and electron cloud, with a small dense gold nucleus at the centre marked with a positive charge.

Simulation of the Atom models – Plum pudding model, Nuclear model and Bohr’s model What it does Three tabs, each showing a different historic model of the atom on an interactive canvas: Plum Pudding (Thomson, 1904) — a glowing purple positive-charge cloud with 8 electrons drifting and wobbling inside it. Purely animated, no interaction needed
