Webagain. When an element formed through the “r” process becomes really heavy (total num-ber of protons and neutrons close to 270), it spontaneously breaks apart through a process called nuclear fission. “The neutrons add very rapidly at a temperature of a few billion degrees, going from iron to uranium in less than 1 second,” Woosley says. Web25 de out. de 2024 · When a massive star collapses in a supernova, the iron at its center could conceivably combine with lighter elements in the extreme fallout to generate heavier elements.

WebThe most common one is the energy process that causes our sun and other stars to shine: in the core of stars small, light atomic nuclei fuse together to form heavier atomic nuclei, releasing huge amounts of energy in the process. Elements up to nickel and iron can be formed in this way. But heavier ones will only form if atomic nuclei capture ...
