Best answer

Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy becausethe total mass of the resulting single nucleus is less than the mass of the two original nuclei.

  • How is energy released in nuclear fusion reactions?

  • Nuclear fusion – Nuclear fusion – Energy released in fusion reactions: Energy is released in a nuclear reaction if the total mass of the resultant particles is less than the mass of the initial reactants. To illustrate, suppose two nuclei, labeled X and a, react to form two other nuclei, Y and b, denoted X + a 鈫?Y + b.

  • Why does nuclear fusion yield more energy than nuclear fission?

  • Why does the nuclear fusion reaction yield more energy than the nuclear fission reaction? Fission only produces more energy than it consumes in large nuclei (common examples are Uranium Plutonium, which have around 240 nucleons (nucleon = proton or neutron)).

  • Why do heavy elements undergo nuclear fission?

  • Since the specific binding energy (binding energy per mass) of intermediate-mass nuclei with atomic numbers and atomic masses similar to 62Ni and 56Fe is greater than the nucleon-specific binding energy of very heavy nuclei, nuclear fission of heavy elements creates exploitable energy, so that energy is released.

  • What is a fusion reactor and how does it work?

  • Two lighter atomic nuclei join in a fusion reaction to form a heavy nucleus, thus releasing energy. Devices meant to harness this power are referred to as fusion reactors.
