Write the approximate mass of a proton, neutron and electron in a.m.u.
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.
An imaginary radioactive element `"_92X^235` decays to form X1; X2; X3; X4; X5 and X6 nuclides, by ejecting two β-particles, followed by α-particles and again two β-particles, followed by α-particle. Represent the various nuclear changes in the form of an equation. State the mass number and atomic number of X6. List the isotopes and isobars in the above nuclear equation.

Draw a simplified labelled diagram of a hot cathode ray tube.
An element 92U238 losses one alpha particle, and then one β-particle and then again one β- particle to get the final nucleus bQa.
(i) Write down the values of a and b.
(ii) State the relationship between the nuclei P and Q.
An isotope of uranium is 92Y238, i.e., it has mass number 235 and atomic number 92.
