This is one of those things where the way you look at it, and what you mean,

determine whether it's even true or not.

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 energetic

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 energetic as

fission per mass per event.

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.


For each gram of reactant fusion produces energy than fission?

For each gram of reactant fusion produces more energy than fission.


Which is more powerful, fusion or fission?

It really depends on what you mean by what is more powerful. Fission is far more destructive in its capabilities, but fusion is less destructive and produces far more energy than fission.


What isdifference nuclear fission and nuclear fission?

The difference between Fusion and Fission is that Fission is easier to do and produces more energy than fusion reactions. However fission can be dangerous and is used in Nuclear reactors. Fusion however is safer and produces less energy but safely. It is quite difficult to cause a Fusion reaction however.

Is a tomic bomb is an example of fusion or fission or annihilation?

An atomic bomb can be a fission bomb or a fusion bomb. Fusion bombs create more energy but fission bombs leave radioactive material and radiation.


Which provides more energy per gram of fuel fission or fusion?

Fusion by more than 400 times.


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.


Compare and contrast fusion and fission?

With nuclear fission, a large atomic nucleus (such as a uranium nucleus) breaks apart into smaller nuclei, and energy is released. With nuclear fusion, small atomic nuclei (such as hydrogen) join to become larger nuclei, and energy is released. Fusion of hydrogen releases much more energy than any other type of either fusion or fission. Note that the dividing line between heavy nuclei and light nuclei is the iron nucleus, which is at the perfect point of nuclear stability, so that neither fusion nor fission of iron nuclei would release any energy.


Compare and contrast nuclear fission and nuclear fu sion?

Fission is when two particles are split to make energy while fusion combines to particles. The result of fission is usually used up radioactive material while fusion results in helium. Fusion makes more energy than fission


What is fusion and fission related to?

Fusion and fission is related to combining (fusion) or splitting (fission) radioactive nuclei, in both cases releasing binding energy (The Strong Atomic Force). Fission is more commonly used in nuclear power plants and A-Bombs, while fusion is more commonly used in H-Bombs and in the Stars.
