How are nuclei heavier than iron formed
WebA star is formed when it is hot enough for the hydrogen nuclei to fuse together to make helium. The fusion process releases energy, which keeps the core of the star hot. Main sequence star WebElements, Formation of. Elements are identified by the number of protons in the nuclei of their atoms. For example, an atom having six protons in its nucleus is carbon, and one having 26 protons is iron. There are over 80 naturally occurring elements, with uranium (92 protons) being the heaviest (heavier nuclei have been produced in reactors).
How are nuclei heavier than iron formed

Webexplosion, elements heavier than iron (such as uranium) are formed and are ejected into space. The ejected material joins up with other dust and hydrogen and begins the process of forming new stars. WebActivity 2: 1. How are elements heavier than helium formed in the stars, particularly until iron? Light elements particularly the hydrogen and helium were formed during the Big Bang, while other elements until Iron were formed thru the fusion of the core of the stars. They were synthesized during the various phases of the evolution of massive stars. …
