Web22 sep. 2024 · Elements are identified by the nuclei of the atoms of which they are made. For example, an atom having six protons in its nucleus is carbon, and one having 26 protons is iron. Heavy elements can be formed from light ones by nuclear fusion reactions; these are nuclear reactions in which atomic nuclei merge together. WebProcesses producing heavier elements As mentioned above, energy can be released by either nuclear fusion or fission reactions and there will be a tendency for material to be …
Web14 nov. 2024 · After the hydrogen in the star’s core is exhausted, the star can fuse helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. Up to this point, the fusion process releases energy. The formation of elements heavier than iron and nickel requires an input of energy. Web30 mrt. 2024 · Elements heavier than iron are formed in the supernova explosions of high mass stars. When the supernova explodes, all the elements produced are thrown out …
