In a nuclear reaction, the mass numbers of the particles play an important part. The relationship between the mass numbers of the reactants and those of the products is that, they should be the same.

∙ 13y agoWell, provided with enough energy, any atom can be a "reactant" of fission and fusion. We're usually concerned about atoms producing exothermic reactions though, which for fission are heavy (mass numbers around 90 and greater), and for fusion are light (mass numbers around 25 and lower).

What are fusion and fission with respect to nuclear physics?
Fission is a nuclear reaction where a heavy atom is split up into lighter elements, thereby producing energy. Fission is commonly used in nuclear power plants, but someday they will use fusion. Fusion is a nuclear reaction where very light elements are fused together under enormous heat and pressure into heavier elements, thereby producing energy. The Sun and all the stars are fusion reactors. Thermonuclear bombs (H-bombs) use fission (an A-bomb) to produce the heat needed for fusion.
How much more energy does fission have than fusion?
This is one of those things where the answer depends on what you mean. The fusion of a deuterium atom and a tritium atom into a helium atom produces about 14.1 million electron volts (MeV). By comparison, the fission of a uranium atom produces about 202 MeV, making a fission event over 14 times as powerful as a fusion event. But we could looked at it another way. A uranium-238 atom as an atomic mass of about 238, and the 202 MeV come from that mass, providing a yield of about 0.82 MeV per unit mass. By contrast, the 14.1 MeV from one deuterium, with an atomic mass of about 2, and one tritium, with an atomic mass of about 3, so the yield is about 2.8 MeV per unit mass, which makes fusion over 3 times as powerful as fission per mass per event.
How do nuclear changes demonstrate the Law of Conservation of Mass and Energy concerning fission and fusion?
Fission and fusion involve the conversion of mass into energy, the total of which is conserved according to E = mc^2. However, at the quantum scale, which is where nuclear reactions take place, it's more accurate to view mass & energy as not two distinct concepts, but one, that of mass-energy. The "mass" of a nucleus is often slightly more than the total mass of it's constituent nucleons, with the excess being in the form of potential mass-energy from the residual strong force locking the nucleons together. In a reaction like fission or fusion, excess mass-energy locked inside the nucleus is released as radiant and kinetic energy.
Nuclear reaction what is lost as energy is created?
Mass.The total mass of the fragment nuclei after fission, or the composite nucleus after fusion,is less than the mass of the nuclei that entered the process.
What is the process by which the nuclei of atoms fuse together producing a tremendous amount of energy?
fusion
What is true about the balance of mass in a fusion reaction?
In a fusion reaction the mass of the products is less than the mass of the reactants.
How are fission and fission similar?
Fusion and fission are similar in that they both reduce mass and thereby release binding energy.
Why is the mass of reactants less than the product in nuclear fission?
A part of mass is transformed in energy.
Why are fission products of same mass as the reactants rarely formed?
During fission, the energy released comes from converting mass into energy (calculated by Einstein's famous equation: E = mc2). Therefore, if a fission reaction releases energy, and it does, that energy came from converting mass into energy, thus reducing the mass of the reactants.
Which is more strong in producing energy the fusion or the fission?
Fusion produces energy more than fission by around 400 times for same mass.
The mass of an atom aftre it under goes fission or fusion?
the mass of the atom after fusion is less than the mass of the input atoms. The mass of the fragment atoms after fission is less than the mass of the original atom.
How does nuclear fission and nuclear fusion get power?
The mass defect due to fission or fusion converts to energy according to the equation: E = m c 2
What are conservation laws obey in each of the nuclear reaction?
for both fission and fusion is E=Mc2 energy is mass and vise verse, in both fission and fusion some mass gets lost in the process. this mass gets converted to energy.
For each gram of reactant fusion produces what energy than fission?
Fusion produces energy more than fission by around 400 times for same mass.
For each gram of reactan fusion produses what energy than fission?
Fusion produces energy more than fission by around 400 times for same mass.
How are fissions and fusion similar?
Fusion and fission are similar in that they both reduce mass and thereby release binding energy.
How nuclear fusion differ to nuclear fission in terms of energy release?
Energy from nuclear fusion is around 400 times more than that of nuclear fission for same mass.
