WebWhich elements are formed during the red supergiant stage of a big star? only small elements like carbon and hydrogen. nearly all the natural elements bigger than iron, but smaller than uranium. big elements like oxygen, neon, magnesium, and silicon, along with the small elements. WebElements heavier than iron are more difficult to make, however. Unlike nuclear fusion of elements lighter than iron, in which energy is released, nuclear fusion of elements heavier than iron requires energy. Thus, the reactions in a star ’ s core stop once the process reaches the formation of iron. Manufacturing heavy 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 ... Webreactions, the nuclei of most elements lighter than iron can be formed (fig. 1). Scientists call this process nucleosynthesis (for “synthe-sis of nuclei”). In stars, these fusion reactions cannot form elements heavier than iron. up until the formation of iron nuclei, these reactions release energy, keeping the star alive. but
