It has something to do with the binding energy per nucleon in the nucleus, but mostly has to do with the range of the residual strong force versus the electromagnetic force. Let's check it out. The dynamics of the nucleus are modestly straightforward and can, for the most part, be reduced to two interactions. Setting aside the intricacies of quantum chromodynamics (QCD), we first consider the protons pushing against each other via the coulomb force, an expression of the electromagnetic force. The electromagnetic force, one of the four fundamental forces in the universe (with the weak interaction or weak force, the strong interaction or strong force, and the gravitational force), operates over distance in a 1/d2 manner. At half the distance, four times the force is felt. At twice the distance, one fourth the force is felt. The thing that holds the nucleus together is the residual strong force, or residual strong nuclear force, the nuclear force or sometimes the (nuclear) binding energy or nuclear glue. (All these terms are sometimes seen.) This force has a quirky nature, and operates in the manner of 1/d4 across distances. You don't have to be a rocket scientist to see that it is really short range compared to the coulomb forces pushing the protons apart. And across large nuclei, it has an increasingly difficult time holding the nucleus together until, at some point, it simply can't do it. Links can be found below to check facts and learn more.
The antonym of nuclear fusion is nuclear fission. Nuclear fusion is the process of combining atomic nuclei to form a heavier nucleus, while nuclear fission is the process of splitting a heavy atomic nucleus into smaller nuclei.
Fusion and fission are two types of nuclear reactions that release energy. Fusion involves combining two light atomic nuclei to form a heavier nucleus, while fission involves splitting a heavy atomic nucleus into lighter nuclei. The main difference is the process by which energy is released: fusion releases energy when light nuclei combine, while fission releases energy when heavy nuclei split.
Fission is the opposite reaction to fusion. Fission involves the splitting of a heavy atomic nucleus into lighter elements, releasing a large amount of energy in the process.
Nuclear fission can only occur in heavy, unstable nuclei, as smaller nuclei are, on the whole, more stable than the largest ones. This only continues down to iron. In elements lighter than iron the heavier nuclei tend to be more stable, so splitting apart a carbon nucleus would absorb energy rather than releasing it. Fusion of carbon releases energy. Such fusion occurs in the cores of some massive stars as they enter their final stages.
Fission is the splitting of a heavy nucleus into lighter nuclei, releasing energy and neutrons. Fusion is the merging of light nuclei to form a heavier nucleus, releasing energy. In fission, the atomic weight of the reactant nucleus is high, whereas in fusion, the atomic weight is low.
Fusion means to combine lighter atoms into a heavier atom. Fission means to split a heavy atom into lighter atoms.
Not typically. When a star burns it starts with fusion of Hydrogen. Later heavier atoms are formed, also by fusion. It is believed that the very heavy atoms, that release energy when split (fission) are only formed by very massive stars . These atoms are also formed by fusion. When one of these very massive stars explodes (super nova) it spews out its atoms and during this process its possible some fission will occur, but for the most part star evolution is a fusion story.
Nuclear energy can be released through nuclear fission, which involves splitting atomic nuclei, or nuclear fusion, which involves combining atomic nuclei. Fission is used in current nuclear power plants, while fusion is still being researched for potential future energy applications.
A fission reactor generates energy by splitting heavy atomic nuclei like uranium or plutonium, releasing a large amount of heat. In contrast, a fusion reactor generates energy by fusing light atomic nuclei, such as hydrogen isotopes, releasing even more energy per reaction but is more challenging to control due to the extreme conditions required for fusion to occur.
Nuclear energy is energy obtained from changes within atomic nuclei. When light atoms combine to form heavier atoms (for example, deuterium is converted to helium), it is called "fusion". When heavy atoms (for example, uranium-235) split, it is called "fission".Nuclear energy is energy obtained from changes within atomic nuclei.

They release energy, which comes out from co2/carbon dioxide. Then they also release a form of gas, which i do not have a name for right now, but yes they do release energy, and c02 which is carbon dioxide.

Nuclear fission and nuclear fusion are both processes that release energy from atoms, but they are different in how they work. Nuclear fission involves splitting a heavy atom into smaller atoms, releasing energy in the process. This is how nuclear power plants generate electricity. Nuclear fusion, on the other hand, involves combining light atoms to form a heavier atom, also releasing energy. This is the process that powers the sun and other stars. The key distinction between the two processes is that fission involves splitting atoms, while fusion involves combining them. Fission typically produces radioactive waste, while fusion produces helium as a byproduct. Fusion also requires extremely high temperatures and pressures to occur, making it more difficult to achieve than fission.
In nuclear energy, energy is released through a process called nuclear fission or fusion. In nuclear fission, heavy atoms like uranium split into smaller ones, releasing a large amount of energy in the form of heat and radiation. In nuclear fusion, lighter atoms combine to form heavier ones, also releasing a significant amount of energy.
Fission
All current nuclear reactors are fission reactors, tritium has no function in a fission reactor, in standard water moderated reactors deuterium also has no function, in heavy water moderated reactors deuterium is the moderator. If we are ever able to make a fusion reactor, deuterium/tritium mix will be used as fuel.
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.
