they combine to small nuclei to smaller unit
Mass.The total mass of the fragment nuclei after fission, or the composite nucleus after fusion,is less than the mass of the nuclei that entered the process.
The process of binding together two light nuclei to form a heavier one is called nuclear fusion. This process releases a large amount of energy and is the same reaction that powers the sun and other stars.
Nuclear fusion is the process of combining two small nuclei to produce heat and one larger nucleus. This process releases a large amount of energy and is the same process that powers the sun and stars.
nuclear fusion
Nuclear energy is held in the strong force holding the protons and neutrons together. There are two ways to release it:Fission of large nuclei into smaller ones - large nuclei (e.g. Uranium-235) are inherently unstable and when struck by a neutron split into two smaller nuclei (fission products - usually about 1/3 and 2/3 the original atomic mass) and 2 or 3 free neutrons plus the released nuclear energy as kinetic energy of these particles.Fusion of small nuclei into larger ones - small nuclei (e.g. Deuterium) are very stable, but when highly compressed and heated to millions of degrees, they will combine with each other releasing nuclear energy as kinetic energy of the product nuclei.Elements in the middle (from iron to lead) cannot undergo either fusion or fission as they have no excess nuclear energy (you can think of them as nuclear "ash").
Nuclear fusion.
This is a nuclear fusion reaction, where two or more small atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process. This type of reaction is the process that powers the sun and other stars.
This process is called nuclear fission. In nuclear fission, a large, less stable nucleus is split into smaller, more stable nuclei, releasing a significant amount of energy in the process. This reaction is the principle behind nuclear power generation and nuclear weapons.
The process of combining nuclei with small masses to form a nucleus with a larger mass is called nuclear fusion. This occurs in stars where intense heat and pressure overcome the electrostatic repulsion between positively charged nuclei, allowing them to fuse together. This process releases a large amount of energy in the form of light and heat.
Mass.The total mass of the fragment nuclei after fission, or the composite nucleus after fusion,is less than the mass of the nuclei that entered the process.
Small nuclei combine to form larger nuclei
Fission and fusion reactions are chain reactions but in different ways. In fission reaction a heavy nuclei is bombarded with a slow moving neutron and this nuclei breaks to produce more such neurons along with generation of new elements. These slow moving neutrons are further used to carry out fission of more such nuclei. This is chain reaction. Fusion reaction are a different class of nuclear reaction in which small nuclei fuse together to produce bigger nuclei along with the generation of energy due to mass defect.. In fusion reaction lot of energy is produced and this energy is used to carry out further reaction. Thus both can be called series reaction.
The process of binding together two light nuclei to form a heavier one is called nuclear fusion. This process releases a large amount of energy and is the same reaction that powers the sun and other stars.
