WebThe heavier elements on the Earth (those with atomic numbers greater than 5) were formed by stellar nucleosynthesis during the life cycles of older stars and supernovae. The earliest nebulae to form in the Universe were made almost entirely of hydrogen and helium.

Webmasses of iron alone.” How stars make elements heavier than iron Elements that are heavier than iron can be assembled within stars through the capture of neutrons—a mechanism called the “s” pro-cess. The process starts when an iron nucleus captures neutrons, thus creating new nuclei. These nuclei can be either stable, that is, they WebSupernovae can leave behind neutron stars. When neutron stars merge, they produce new nuclei, including elements that are heavier than iron. Other stars become white dwarfs as they die. These white dwarfs may also later merge and synthesize nuclei of elements. DOE Office of Science: Nucleosynthesis Contributions
Web8 de jul. de 2024 · Some elements were created naturally, while others were created through man-made means.
