Consider a radioactive nucleus A which decays to a stable nucleus C through the following sequence: A → B → C Here B is an intermediate nuclei which is also radioactive. Considering that there are N0 atoms of A initially, plot the graph showing the variation of a number of atoms of A and B versus time.
Here, in the above graph:
At t=0, NA = N0
NA falls off exponentially with the increase in time.
As a result, the number of atoms of B increases, it will be maximum once and then decays to zero at
