In a nuclear reaction, the total (relativistic) energy is conserved. It means that mass, energy and momentum all are conserved.

  • The total momentum of the interacting particles before and after a reaction are the same.
  • Energy along with rest mass energy, is conserved in nuclear reactions
  • According to Einstein's equation E=mc2 , if energy is conserved , mass is also conserved.
