Consider a radioactive material of half-life $1.0 \, minute$. If one of the nuclei decays now, the next one will decay
After $1$ minute
After $\frac{1}{{{{\log }_e}\,2}}$ minute
After $\frac{1}{N}$ minute, where $N$ is the number of nuclei present at that moment
After any time
If $T$ is the half life of a radioactive material, then the fraction that would remain after a time $\frac{T}{2}$ is
Give the equation form of exponential law.
The decay constant of the end product of a radioactive series is
Which sample contains greater number of nuclei : a $5.00- \mu Ci$ sample of $_{240}Pu$ (half-life $6560\,y$) or a $4.45 - \mu Ci$ sample of $_{243}Am$ (half-life $7370\, y$)
The half life of a radioactive substance against $\alpha - $ decay is $1.2 \times 10^7\, s$. What is the decay rate for $4.0 \times 10^{15}$ atoms of the substance
