What do you understand by radioactive decay? An isotope of Uranium `""_92^238 "U"` is radioactive and changes into Thorium 92 by the emission of an alpha particle. Write a symbolic equation for this decay process.
Assertion (A): In the process of nuclear fission, the amount of nuclear energy generated by the fission of an atom of uranium is so tremendous that it produces 10 million times the energy produced by the combustion of an atom of carbon from coal.
Reason (R): The nucleus of a heavy atom such as uranium, when bombarded with low energy neutrons, splits apart into lighter nuclei. The mass difference between the original nucleus and the product nuclei gets converted to tremendous energy.
