is the process that powers active stars, the hydrogen bomb and experimental devices examining fusion power for electrical generation. Fusion. Nuclear fusion is an atomic reaction that fuels stars. Fusion inside stars transforms hydrogen into helium, heat, and radiation. Nucleon. a collective name for two particles: the neutron and the proton. The star eventually will cool down and die. Nuclear fusion is a process that combines nuclei in order to release energy. Most of the stars in the universe are main sequence stars. This promotes the fusion of heavier and heavier elements, ultimately forming all the elements up to iron. Nucleosynthesis definition, the formation of new atomic nuclei by nuclear reactions, thought to occur in the interiors of stars and in the early stages of development of the universe. Main sequence stars are stars that are fusing hydrogen atoms to form helium atoms in their cores. The sun is a main sequence star. The star uses a process called nuclear fusion to generate energy. On Earth it is very difficult to start nuclear fusion reactions that release more energy than is needed to start the reaction. It is also called "hydrogen burning", which should not be confused with the chemical combustion of hydrogen in an oxidizing atmosphere. Nuclear fusion. is the process by which two or more atomic nuclei join together, or "fuse", to form a single heavier nucleus. All of the atoms in the universe began as hydrogen. The fusion of hydrogen nuclei uses up hydrogen to produce helium and energy. Nuclear fusion Jump to: navigation, search This article is about the science behind nuclear fusion.For its use in producing energy, see fusion power.. Nuclear Fusion: Nuclear fusion is the process by which nuclear reactions between light elements form heavier ones (up to iron). Nuclear fusion definition is - a process in which the nuclei of atoms are joined. Stellar nucleosynthesis is the process by which elements are created within stars by combining the protons and neutrons together from the nuclei of lighter elements. Hydrogen fusion (nuclear fusion of four protons to form a helium-4 nucleus) is the dominant process that generates energy in the cores of main-sequence stars. In fusion, many nuclei (the centers of atoms ) combine together to make a larger one (which is a different element). Hydrogen is the fuel for the process. See more. As the hydrogen is used up, the core of the star condenses and heats up even more. Nuclear fusion, process by which nuclear reactions between light elements form heavier elements (up to iron). In cases where the interacting nuclei belong to elements with low atomic numbers (e.g., hydrogen [atomic number 1] or its isotopes deuterium and tritium), substantial amounts of energy are released.
