Radioactive decay occurs for all nuclei with Z … Web12 de set. de 2024 · N = N0 2n. If the decay constant (λ) is large, the half-life is small, and vice versa. To determine the relationship between these quantities, note that when t = T1 / 2, then N = N0 / 2. Thus, Equation 10.4.4 can be rewritten as. N0 2 = N0e − λT1 / 2. Dividing both sides by N0 and taking the natural logarithm yields.
