Radioactive Decay Simulation — Description Half-Life Simulation 64 radioactive atoms are displayed in a grid. Each atom glows and shakes while unstable. When it decays, it flashes and dims. The live graph on the right plots actual decay data against the theoretical curve N(t) = N₀ · e^(−λt) in real time. Choose from five AQA […]

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

Radioactive Decay Simulation — Description The simulation shows 48 unstable nuclei arranged in a grid, each decaying randomly over time following the exponential decay law N(t) = N₀ · e^(−λt). Students can select five AQA-relevant isotopes from the dropdown — Carbon-14, Polonium-210, Radium-226, Technetium-99m, and Sodium-22 — each with its correct decay type (α, β⁻,

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.
