The end product of the $(4n + 2)$ radioactive disintegration series is:

In the carbon cycle,from which hot stars obtain their energy,the $_6C^{14}$ nucleus is

Assertion : Nuclear binding energy per nucleon is in the order $_4^9Be > \,_3^7Li > \,_2^4He$.
Reason : Binding energy per nucleon increases linearly with the difference in the number of neutrons and protons.

If the mass defect of a nuclide is $3.32 \times 10^{-26} \ g$, its binding energy in $MeV$ is:

Positron emission results from the transformation of one nuclear proton into a neutron. The isotope thus produced possesses

Which element is the end product of each natural radioactive series?
