The process of combining two nuclei to form a heavier nucleus and thereby releasing energy is nuclear fusion. When a neutron strikes an atom of uranium-235, the atom captures the neutron, becoming an atom of uranium-236 with an excited nucleus. The U-236 nucleus vibrates rapidly and cannot hold itself together; it splits into several pieces (smaller atoms, free neutrons, etc.) in a process called nuclear fission (fission means "division"), releasing an enormous amount of heat energy and gamma rays.
Fastern your seatbelt. We've got some ground to cover. But it won't be too difficult to grasp the fundamentals. In either fission or fussion, we are taking about nuclear processes, i.e., the physics of nuclear structure and construction/destruction of that nucleus. The big difference is fusion is the "building" of atomic nuclei, and fission is the "breaking" or "splitting" of atomic nuclei. Fusion is the bonding of atomic nuclei or nuclear particles (nucleons - protons and neutrons) to make "bigger" or "heavier" atomic nuclei. Fission, on the other hand is the splitting of the atom. As the atoms fuse or split they release energy. Lots of it. And most of it is heat energy. In nuclear weapons, the energy is released "all at once" to create a blast. If the energy is released in a "controlled" way, we can release heat at a "useable" rate and apply it to boiling water to make steam. In fusion, protons or neutrons or the nuclei of atoms are forced together and are fused to make a new atomic nucleus. The release of lots and lots of energy accompanies this reaction. That's what powers stars. Currently we can't really do any fusion reactions to make useful power. There are a few agencies working on fusion devices, but the high temperatures required to attain fusion require very special materials and controls. The current "state of the art" fusion facility is the International Thermonuclear Experimental Reactor (and a link is provided). Fusion is unlikely to become a useful source of power for many years. But what about fission? Nuclear fission involves the splitting of large atoms, usually uranium (or sometimes plutonium). When large atoms fission they produce two smaller atoms or fission fragments (and a couple of neutrons and lots of energy). The total mass of the products is less than the mass of the original atom. This mass difference is turned into energy in accordance with the Einstein equation E=mc2. Most of the energy appears in the recoil of the fission fragments, and the heat that is generated is considerable. It is that heat that we capture to turn water into steam to generate electricity. Nuclear Fission: Basics When a nucleus fissions, it splits into several smaller fragments. These fragments, or fission products, are about equal to half the original mass. Two or three neutrons are also emitted. Nuclear Fission The sum of the masses of these fragments is less than the original mass. This 'missing' mass (about 0.1 percent of the original mass) has been converted into energy according to Einstein's equation. Fission can occur when a nucleus of a heavy atom captures a neutron, or it can happen spontaneously. = Nuclear Fusion = Nuclear Fusion Nuclear energy can also be released by fusion of two light elements (elements with low atomic numbers). The power that fuels the sun and the stars is nuclear fusion. In a hydrogen bomb, two isotopes of hydrogen, deuterium and tritium are fused to form a nucleus of helium and a neutron. This fusion releases 17.6 MeV of energy. Unlike nuclear fission, there is no limit on the amount of the fusion that can occur.
Nuclear fusion is taking two different atoms and combining them in to one atom, while nuclear fission takes one atom and seperates it into two atoms.

During nuclear fusion, light nuclei merge (fuse), forming heavier nuclei and excess energy.
During nuclear fission, heavy nuclei split, forming lighter nuclei and excess energy.
The suns energy is produced by nuclear fusion
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
splitting apart vs. joining together

Definition: energy from nuclear fission or fusion: the energy released by nuclear fission or fusion
Fission and fusion are different nuclear reactions.
The Sun get it power by nuclear FUSION not by nuclear 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.
