Half-life

Real World Example

Imagine you're trying to eat a large pizza by yourself, and you decide to eat half of what's left every hour. Just like how you're gradually reducing the pizza by half over consistent time intervals, a radioactive isotope decreases in quantity as it decays, with half of its atoms breaking down over a specific period known as the half-life. In both cases, whether it's the pizza or the radioactive atoms, each 'half-life' or hour results in 50% of what's left disappearing, illustrating the predictable and systematic reduction over time.
