In a nuclear reaction mass is conserved

Web451 Nuclei In both β-and β + decay, the mass number A remains unchanged. In β-decay, the atomic number Z of the nucleus goes up by 1, while in β + decay Z goes down by 1. The basic nuclear process underlying β-decay is the conversion of neutron to proton n → p + e – + ν (13.24) while for β + decay, it is the conversion of proton into neutron p → n + e + + ν … WebTotal mass–energy is also conserved: the energy produced in the decay comes from conversion of a fraction of the original mass.

WebIn nuclear engineering, a neutron moderator is a medium that reduces the speed of fast neutrons, ideally without capturing any, leaving them as thermal neutrons with only minimal (thermal) kinetic energy.These thermal neutrons are immensely more susceptible than fast neutrons to propagate a nuclear chain reaction of uranium-235 or other fissile isotope by … WebWhy is mass not conserved in a nuclear reaction? Mass in nuclear reactions is not strictly conserved due to this principle of mass and energy being quite similar. We know that nuclear reactions release a lot of energy. This energy, though, is actually mass that is lost from nucleons, converted into energy, and lost as the mass defect.
