What forces hold nuclei together and mediate nuclear processes?
Energy and Matter: In nuclear processes, atoms are not conserved, but the total number of neutrons plus protons is conserved.
PS1:C Nuclear Processes: Nuclear processes, including fusion, fission, and radioactive decays of unstable nuclei, involve release or absorption of energy. The total number of neutrons plus protons does not change in any nuclear process.
