7.17 understand that a nucleus of U-235 can be split (the process of fission) by collision with a neutron, and that this process releases energy in the form of kinetic energy of the fission products
Fission: If unstable nuclei split up to form stable nuclei, the process is called Fission. Urnaium-235 can also be split up by collide a neutron with the nuclei. As it is done so, the nucleus becomes unstable and split up to form Krypton and Barium (stable atoms) and three nucleus and gamma rays.
