WebHalf life formula. By using the following decay formula, the number of unstable nuclei in a radioactive element left after t can be calculated: N (t) = N_0 \times 0.5^ { (t/T)} N (t) = N 0 × 0.5(t/T) In this equation: N (t) refers to the quantity of a radioactive element that exists after time t has elapsed. N (0) refers to the initial amount ... Web16 nov. 2024 · Half life equation.
