Assertion: In the process of nuclear fission, the fragments emit two or three neutrons as soon as they are formed and subsequently emit particles. Reason : As the fragments contain an excess of neutrons over protons, emission of neutrons and particles bring their neutron/proton ratio the to stable values

Staements I: The fission of a heavy nucleus is always accompanied with the neutrons along with two product nuclei. Staements II: For a lighter stble nuclide, the N/Z ratio has to be slightly greater than 1.
