If a heavy nucleus were to fission into only two product nuclei, they would be very unstable. In what way? Why? How would they decay?
GGenerally fission of nuclides contain an axis of neutrons and are therefore highly unstable they undergo beta decay until they form stable end products.
THEORY OF NUCLEAR FISSION
Explaination on the bsis of liquid drop model
the nucleus is assumed as a liquid drop of spherical shape which is incompressible and has a uniform positive charge.The distance between the positively charged Proton tends to split the nucleus but the forces of the surface tension and short range nuclear forces hold the nucleons together. When A nucleus captures a neutron its equilibrium is disturbed and it begins to oscillate about its spherical shape due to the energy of the absorb neutron.when the excitation energy is sufficiently large the compound nucleus the form into a dumb-bell shaped structure.The oscillations eventually lead to the fission of the nucleus into two fragments accompanied by emission of neutrons.
The nuclie Fission products are also unstable they attain stability by emitting beta rays, Gamma Rays and more neutrons.
