For a radioactive nuclide, what is the correct relation between the Average Life Period () and the H — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

Average life ($T$) is the reciprocal of the decay constant ($T = 1/\lambda$). Since $\lambda = 0.693 / T_{1/2}$, substitution yields $T = T_{1/2} / 0.693$, which simplifies exactly to $T = 1.44 \times T_{1/2}$.
