Visualize radioactive decay — half-life, decay curves, and particle emission
Radioactive atoms decay randomly, but statistically follow N(t) = N₀·(½)^(t/t½). The half-life t½ is the time for half the atoms to decay. After 1 half-life: 50% remain. After 2: 25%. After 3: 12.5%. This exponential decay is used in carbon dating, nuclear medicine, and understanding reactor safety. Each dot represents an atom — orange = undecayed, dark = decayed.
