A nuclide of an alkaline earth metal under goes radioactive decay by emission of the $\alpha$-particles in succession. The group of the periodic table to which the resulting daughter element would belong is:
Gr. 4
Gr. 6
Gr. 14
Gr. 16
Solution
After decay of radioactive element, the last element (stable) $\mathrm{Pb}$ is obtained which belongs to group 14 of periodic table.
