Radioactive Decay for a redox reaction

Built for engineers using it for real design work. Go from concept to a running model in the browser, then scale to the cloud when needed. Simulate a redox reaction live below — adjust the inputs and watch it respond, right in your browser.

Controls

Every half-life, half the remaining atoms decay. After n half-lives, only (1/2)ⁿ is left — the basis of carbon dating and nuclear physics.

Governing equation

Reading this result: Each half-life removes half of whatever remains, so the curve falls steeply at first and then flattens into a long tail.
