Nuclear fission is the splitting up of big atomic nuclei. Uranium is quite a large nuclei. Each time a uranium atom splits up, it spits out two or three neutrons. One of which might hit another nuclei causing it to split - thus keeping the chain reaction going. The uranium atom - when hit by a neutron splits into Barium and Krypton.

How do neutrons electrons and protons relate to nuclear energy?
These are the constituents of atoms. Nuclei are made up of protons and neutrons. Useful nuclear energy is only obtained from a few nuclei which can be made to fission and release energy. The two main ones are Uranium235 and Plutonium239.
What does energy made from split atoms mean?
Energy made from split atoms refers to nuclear energy, which is generated through a process called nuclear fission. During nuclear fission, the nucleus of an atom is split into smaller parts, releasing a significant amount of energy in the form of heat. This heat can then be harnessed to generate electricity in nuclear power plants.
How does the energy released by fusion compare in magnitude with that released by fission?
In a fission reactor which has been operating at a steady power level, on shutdown the fission reactions stop at once, but the radioactivity of the fission products in the fuel still produces thermal energy. This is about 6.5 percent of the previous power level immediately, dropping to about 1 percent after 1 hour. In the case of fusion, there are no fission products so this comparison does not exist, in fact if fusion reactors can ever be made, this is one of the advantages over fission reactors.
What is fission made from?
Nuclear fission occurs in a few elements and then only in certain isotopes, best known are uranium-235 and plutonium-239. In these cases capture of a neutron causes the nucleus to split up into two lighter pieces, and for neutrons to be emitted. This enables a chain reaction to be started.
What causes nuclear reactions?
an atom has a part called nucleus which can be split apart.When this is done a tremedous amount of energy is released.The energy is both heat and light if this is energy is let out slowly then it can be harnessed to make electricity if it is let out all at once it will cause nuclar energy bdgrejdxhjhtm
Comparison of fission fusion and transmutation?
Fission is the splitting of heavy nuclei, mostly Uranium235 but also Plutonium 239, which is made to happen in nuclear fission reactors, and releases energy. Transmutation of elements occurs in this process as when the heavy nucleus splits, two lighter nuclei of other elements such as caesium, strontium, iodine, are formed, these are the fission products. Fusion is the joining together of two nuclei, the ones being experimented with being deuterium and tritium, both isotopes of hydrogen. These transmute to helium during fusion.
Can a atom divide into smaller particles?
Atoms consist of a nucleus made up of protons and neutrons, surrounded by electrons. Atoms can undergo nuclear reactions, such as fission or fusion, which can split the nucleus into smaller particles. However, in normal chemical reactions, atoms do not divide into smaller particles.
What element is best suited for nuclear fission?
Uranium-235 is commonly used for nuclear fission due to its ability to undergo a chain reaction when bombarded with neutrons. Its nucleus can easily split into smaller nuclei, releasing a large amount of energy in the process.
Does eubacteria reproduce by binary fission?
Yes, eubacteria reproduce by binary fission, which is a form of asexual reproduction where a single cell divides into two identical daughter cells. This process allows for rapid multiplication of eubacteria populations.
How is the energy in the reactor made to drive a turbine?
The fuel in the core of a nuclear reactor goes into a chain reaction of nuclear fission. This happens because atoms of some isotopes in the fuel undergo spontaneous fission, producing neutrons, which cause other atoms to undergo fission, and so on. The fission produces a lot of heat. The heat is typically used to boil water, which is used to turn a turbine. And finally, the turbine turns a generator to make electricity.

What elements are made by a nuclear fission reaction?
Nuclear fission reactions primarily produce two main elements: fission fragments (such as cesium, strontium, and xenon) and neutrons. These fission fragments can further undergo radioactive decay and produce additional elements.
What three isotopes that can undergo nuclear fission?
Three isotopes that can undergo nuclear fission are uranium-235, plutonium-239, and uranium-233. When these isotopes absorb a neutron, they become unstable and split into smaller fragments, releasing energy in the process.
Can hydrogen undergo alpha decay?
No, it cannot. Fission is the "splitting" of an atom, and a hydrogen atom will not fission. Some hydrogen atoms have a neutron stuck to the proton in their nucleus. Some even have two neutrons stuck to that proton. These neutrons can be "knocked loose" in something like a nuclear chair reaction in a weapon. The neutrons then can contribute to the building of the nuclear chain reaction. But fission doesn't happen to hydrogen.
