which one has greater impact fission reaction or fussion reaction?

Answer 1

Fusion reaction coz the energy liberated thru fusionis reactions was some M.ev higher than fission reaction...............fission reaction takes place in Atom bomb where as fusion in the sun which liberates some million electron volts of energy.............

Answer 2

"Has" or "has had" a greater impact? Fusion reaction technology would have the greatest impact if it could be perfected in a power plant. Fusion reactors would far surpass energy output and capability of current fission reactors. Problem is the only working fusion technology that exists today is in our nuclear weapons--let's hope we never see the impact of those.
In history, only fission technology has been implemented. All the world's nuclear reactors are fission, creating waste when making energy. And, the only time a nuclear weapon has been deployed was the bombing of Japan by US in WWII which was a fission "atomic device".
So, so far only fission technology has had any real impact upon history, both good and bad. Hopefully, we can perfect fusion technology so it will have a very positive impact on our quality of life.

Answer 3

Actually, nuclear fusion has got a greater impact. Since, the energy evolved is so tremendous, the present technology has not been able to harness the force. Hence, these days we use nuclear fission only. The energy released during fission is also tremendous but not as much as fusion's. Also we have the technology to consume the energy released by fission and hence are using fission these days.

Answer 4

if u mean impact is after effect then i say fission as radiations ,sound , heat and light cause a lot of damage .and in comparison to fission or fusion the quantity of energy released is more in fusion but on living being loss scale both are too much.

Answer 5

nuclear fusion reaction has great impact.due to this reaction lots lots of lots of energy is produced.this process is occured in sun to produce helium from hydrogen.
nuclear reaction:reactions between light elements form heavier ones (up to iron). Substantial amounts of energy are released in cases where the interacting nuclei belong to elements with low atomic numbers.

Fusion reactions constitute the fundamental energy source of stars, including the Sun. Stellar evolution can be viewed as the passing of a star through various stages as thermonuclear reactions and nucleosynthesis cause compositional changes over long time periods. Hydrogen “burning” initiates the fusion energy source of stars and leads to the formation of helium. Generation of fusion energy for practical use also relies on fusion reactions between the lightestelements that burn to form helium. In fact, the heavy isotopes of hydrogen, deuterium ( 2/1H, or D) and tritium ( 3/1H, or T), react more efficiently with each other and yield more energy per reaction than do two hydrogen nuclei ( protons) when they undergo fusion. The deuterium nucleus has one proton and oneneutron, while that of tritium consists of a proton bound together with two neutrons.

Fusion reactions between light elements, like fission reactions that split heavy elements, release energy due to a key feature of nuclear matter. A parameter called the binding energy of the nucleus is a measure of the efficiency with which its constituent nucleons are bound together. Take, for example, an element withZ protons and N neutrons in its nucleus. The element's atomic mass number or atomic weight, A, is Z + N and its atomic number is Z. The binding energy is the energy associated with the mass difference between the Z protons and N neutrons considered separately and the nucleons bound together (Z + N) in a nucleus of mass, M. The formula is:
B=[Zmp+Nmn-M(Z,N)]c2 (square of c)
where m p and m n are the proton and neutron masses, and c is the speed of light. It has been determined experimentally that the binding energy per nucleon is a maximum of about 8.8 MeV at an atomic mass number of approximately 60. Accordingly, thefusion of lighter elements or the splitting of heavier ones generally leads to a net release of energy.
