Calculate the remaining quantity of a substance after exponential decay
Formula: $N(t) = N_0 \cdot \left(\frac{1}{2}\right)^{\frac{t}{t_{1/2}}}$
Where $N(t)$ is the remaining amount, $N_0$ is the initial amount, $t$ is the elapsed time, and $t_{1/2}$ is the half-life.
Where $N(t)$ is the remaining amount, $N_0$ is the initial amount, $t$ is the elapsed time, and $t_{1/2}$ is the half-life.

⚠️ Radioactive decay is a stochastic (random) process that follows first-order kinetics. Calculations represent statistical averages and may not perfectly predict the exact continuous behavior of extremely small samples of atoms.
