Consider a radioactive nucleus $A$ which decays to a stable nucleus $C$ through the following sequence : $A \to B \to C$ Here $B$ is an intermediate nuclei which is also radioactive. Considering that there are $N_0$, atoms of $A$ initially, plot the graph showing the variation of number of atoms of $A$ and $B$ versus time.

Considering that there are $N_0$, atoms of $A$ initially, plot the graph showing the variation of number of atoms of $A$ and $B$ versus time.
Here at an instant of time when $\mathrm{N}_{\mathrm{B}}=\left(\mathrm{N}_{\mathrm{B}}\right)_{\max }^{\prime}$ growth rate and decay rate have become equal for element B. Before this time, its growth rate is more (than its decay rate) and after this time its decay rate is more (than its growth rate).
