How are heavier elements formed
WebThis happens because the nuclear binding energy is at its maximum at iron. Hence lighter elements were made in ordinary stars, using fusion. However, heavier elements were made in supernovas, as huge amounts of extra energy are released during the explosion, some of which is used to force heavy nuclei together and create heavier elements. Share. Web8 de mar. de 2024 · The most common elements, like carbon and nitrogen, are created in the cores of most stars, fused from lighter elements like hydrogen and helium. The …

WebElements heavier than iron are produced mainly by neutron-capture inside stars, although there are other more minor contributors (cosmic ray spallation, radioactive decay). They …
WebHá 48 minutos · Because so many fewer stars had lived and died at that time in the universe, such heavier elements were more scarce. Observing this galaxy was aided by a phenomenon called “gravitational lensing” that occurs when an immense amount of matter, like a grouping of galaxies, creates a gravitational field that distorts and magnifies light … Web23 de dez. de 2024 · Brandon Chang.
