Nuclear fission is the breaking down of an atom's nucleus. This happens because of the small range of activity of the strong interaction, the force that holds the nucleus together. When a atom's nucleus exceeds the size/range the strong interaction can hold, the whole nucleus will breakdown, releasing large amounts of energy. The protons and neutron will scatter go into other nuclei (plural), breaking the other nuclei down, causing chain reactions and releasing more energy. This energy is used to boil water like burning coal in conventional power plants.
Nuclear fusion cannot occur on Earth. It only occurs in the sun and other stars.

∙ 13y agoIt is the strong and weak nuclear force that binds the protons and nutrons together in the nucleus of an atom. When these bonds break to create new atoms (fission) or form to create new atoms (fusion), they release a lot of energy.

One heavy atomic nucleus splits into two or more separate lighter atomic nuclei.
The masses of all the pieces add up to less than the mass of the first one.
Fusion:
Two light atomic nuclei join up and form a single heavier atomic nucleus. The mass
of the combination is less than the sum of the masses of the original two.
In both cases, the missing mass leaves the site of the conversion in the form of energy.

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.
What is the advantage to producing energy from fusion of hydrogen?
If it can be made to work, the two main advantages would be: 1. A source of deuterium from water that would never run out, 2. It would not produce the fission products that are a problem of disposal with fission reactors
What is nuclear energy made from?
In general, nuclear energy comes from the energy associated with atomic nuclei. There is nuclear fusion, which happens in stars and in fusion weapons, and there is nuclear fission. Nuclear fusion is the "combining" of lighter atomic nuclei to create heavier ones, and many fusion reactions release energy. (Again, think of stars.) In contrast, nuclear fission is the "splitting" of atomic nuclei to release energy. The latter is technology that we've come to use fairly widely, and we have developed fission nuclear weapons and the nuclear reactor to tap nuclear energy via fission. Let's look at the latter device, the reactor. The fission of nuclear fuel (also known as atomic fuel, such as uranium or plutonium) is where we get nuclear energy. And what happens during nuclear fission is that the nuclei of fuel atoms absorb neutrons and fission (split), releasing lots of energy. In fission, that larger atomic nucleus breaks into a pair of smaller ones, and these fission fragments recoil with a lot of kinetic energy. The fuel traps the fission fragments, and the energy they came away with is converted into thermal energy in the fuel. We derive nuclear energy by tapping the energy of formation of atomic nuclei via fusion or fission. This is advanced technology that is less than a century old. We're still working to use it well and wisely.
What is the principal source of stellar energy?
well htey get there energy from burning the gasses that it is made of like our sun
What is an alternate energy source produced from atomic reaction?
Nuclear fission is when a neutron is fired at an element with a high atomic number, which splits and releases more neutrons and energy as a result. Nuclear fusion occurs in stars and experimental reactors.
Is fusion or fission the main energy source for stars?
Nuclear Fusion
Outline on nuclear energy?
Definition: energy from nuclear fission or fusion: the energy released by nuclear fission or fusion
Is energy released during fission but absorbed during fusion?
Energy is released during fusion and fission.
Why are fission and fusion called nuclear energy?
Nuclear energy is the source of the energy produced by both fission and fusion. Per Einstein's equation E = mc2 matter may be converted into energy. In fission, the nuclei of heavy atoms like Uranium or Plutonium are split into less heavy elements. Byproducts of fission are nuclear energy and neutrons that may be used to sustain the nuclear fission process as in a reactor or a bomb. In fusion, two nuclei are merged (or fused) to form a heavier element. Often two Hydrogen atoms are fused to form a Helium atom. Fusion is the process that occurs in our sun. Both fission and fusion result in the conversion of a small amount of the matter in the nuclei of the source atom(s) into energy. Therefore, both may be considered nuclear energy.
What is the difference between the use of fission as an energy source?
The difference between the use of fission and fusion as an energy source is that in fusion reaction, 2 or more light atomic nuclei fuses to form single heavier nucleus while in fission reaction, heavy atomic nucleus is usually splited into smaller nuclei, other particles and radiation.
Which is the cause of the sun energy?
Nuclear fission is the source of the sun's energy. It is a process in which an atom of hydrogen fuses with another atom of hydrogen, releasing large amounts of energy in the process. It is quite the opposite of nuclear fission, which is the source of atomic energy.
How is the nuclear energy in use different from fusion energy?
Because it is a fission process, not fusion
Which process would release energy from gold fission or fusion?
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.
Energy release of fusion compared to fission?
fusion=bigger boom
Fission and fusion are example of what kind of energy?
Nuclear energy.
For each gram of reactant fusion produces energy than fission?
For each gram of reactant fusion produces more energy than fission.
