What's the difference between a nuclear fusion and a nuclear fission?

Answer 1

Nuclear fusion is the merger of multiple nuclei
Hydrogen fusion releases the energy that causes stars to shine and hydrogen bombs to explode
Fusion of heavier elements causes Supernovas
The only fusion reactions thus far produced by humans to achieve ignition are those which have been created in hydrogen bombs. Scientist continue to research fusion of heavier elements but it has not resulted in anything feasible as of yet.
Anti-matter is one area of research

Nuclear fission is the splitting of atoms and has been in wide use for many years and it produces energy for nuclear power and to drive explosion of nuclear weapons

Answer 2

As the names suggest, fusion is a combination of atoms while fission is the splitting of an atom.
An example of the latter is the radioactive element Uranium. When fission occurs there is a release of a tremendous amount of energy which was proposed by Einstein as equal to its mass multiplied by the velocity of light squared.
No wonder a teaspoon of pure Uranium can light the city where you live for months.

Answer 3

Nuclear fission reaction is one in which heavier/larger nucleus is split into smaller nuclie.
It gives out more energy. Ex: As in atom bomb

Nuclear fusion is the one in which smaller nuclei in the presence of large energy combine with each other to result a heavier nuclues.

Answer 4

Nuclear fission is the splitting of heavy nuclei to create lighter ones with more binding energy per nucleon; since the binding energy is negative, energy is released. Fission is exhibited by uranium, plutonium, and thorium, as well as by some heavy artificial elements.

Fusion is the combining of light nuclei to create heavier ones, again with more binding energy per nucleon. The energy change per nucleon is larger than with fission, so more energy is released. The first hydrogen bomb fused deuterium to make helium; some tritium was used to help ignite the reaction.

Answer 5

1)NUCLEAR FISSION IS THE BREAKDOWN OF A HEAVY RADIOACTIVE NUCLEUS INTO LIGHTER NUCLEI WHEREAS NUCLEAR FUSION IS JOINING OF LIGHT NUCLEI TO FORM A STABLE HEAVY NUCLEUS.

2)NUCLEAR FISSION TAKES PLACE AT ORDINARY TEMPERATURES WHEREAS NUCLEAR FUSION TAKES PLACE AT A TEMPERATURE OF 4,000,000 DEGREE CELSIUS.

3)THE PRODUCTS OF NUCLEAR FISSION ARE RADIOACTIVE IN NATURE AND CAUSE DISPOSAL PROBLEM WHEREAS THE PRODUCTS OF NUCLEAR FUSION ARE NON-RADIOACTIVE.

4)THE NUCLEAR FISSION REACTION CAN BE CONTROLLED AND THE ENERGY RELEASED CAN BE USED TO PRODUCE ELECTRICITY WHEREAS FUSION CANNOT BE CONTROLLED AND HENCE THE ENERGY RELEASED CANNOT BE UTILIZED.

Answer 6

Fusion is where things are "welded together" so a combination takes place. Hydrogn is fused to Helium on the sun, so helium is heaver than hydrongen

Fission is like where they fizzle off; Thus an element would give off paticles to fizzle away and become a ligher element. Uranium 238 fizzles away to a ligher element.

Answer 7

fusion = putting small atoms together to make bigger ones
fission = spliting large atoms apart to make smaller ones
