In a nuclear fusion reaction, one deuterium atom (one proton and one neutron) combines with one tritium atom (one proton and two neutrons) to form one helium atom (two protons and two neutrons) plus a free neutron. In this reaction a huge amount of energy is released. Using Einstein’s idea of mass–energy equivalence, what can you conclude about the mass of the final products compared to the mass of the initial fuel?
