Question

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.

Solution

Verified by Toppr

At $t = 0, N_{A} = N_{0} .$

As time increases, $N_{A}$ falls off exponentially,

the number of atoms of B increases, becomes maximum and finally decays to

zero at $\infty$ (following exponential decay law).
