What is nuclear fusion? Explain with an example. Write the equation of the reaction involved.
What are the advantages and disadvantages of using nuclear fuel for generating electricity?
The heat energy released during nuclear fission and fusion is due to the:
(a) conversion of stored chemicals into energy
(b) conversion of momentum into energy
(c) conversion of mass into energy
(d) conversion of magnetism into energy
A nuclear reaction is represented by the following equation:

What type of bomb is based on similar type of reaction?
What do you mean by nuclear energy? What is responsible for its release?
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.
A certain nucleus X has a mass number 14 and atomic number 6. The nucleus X changes to `"_7Y^14` after the loss of a particle. Name the particle emitted.
