Why is iron the only element that can be produced in stars?
All elements (except hydrogen) are produced in stars through nuclear fusion (under tremendous heat, two hydrogen atoms fuse into one helium plus release pure energy). When the hydrogen is all fused, helium is fused into heavier elements at a higher temperature, then those are fused and so on until we get to iron. Iron is the element that will cause a star to collapse and then explode violently in a supernova. The explosion causes further fusion and creates still heavier elements.
Where is iron made mostly from?
Iron is fused within a star's core. When sufficient iron has accumulated and it begins to fuse, the energy of that fusion is too great and the star explodes creating all the heavier elements.up ya bum
Is iodine heavier than iron?
No, atomically Iron is a heavier element
What happens during nuclear fusion and fission?
In nuclear fusion, two atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process. This is the process that powers the sun and other stars. In nuclear fission, a heavy nucleus splits into two or more lighter nuclei, along with the release of energy and neutrons. This process is used in nuclear power plants to generate electricity.
What elements up to iron form by alpha particle capture?
Alpha particle capture primarily leads to the formation of elements up to iron (Fe) through nucleosynthesis processes in stars. When alpha particles (helium nuclei) are captured by lighter nuclei, they can combine to form heavier elements, such as carbon, oxygen, and ultimately iron. This process is significant in stellar environments, particularly during helium burning phases, where the fusion of alpha particles contributes to the nucleosynthesis of elements in the periodic table up to iron. Beyond iron, fusion becomes energetically unfavorable, leading to the formation of heavier elements through other processes like neutron capture.
How are elements with nuclei larger than iron nuclei formed?
Supernova form heavier elements

Which nuclear fuel is there in the sun?
At this point in time hydrogen is being fused into helium. Many, many years down the line, as the hydrogen runs out, the sun will begin fusing heavier and heavier elements for fuel. At least to iron.
Explain how heavier elements are formed from hydrogen within the core of a star?
Heavier elements are formed through nuclear fusion reactions in the core of a star. Hydrogen atoms are fused together under high pressure and temperature to form helium. Further fusion reactions involving helium nuclei lead to the formation of heavier elements like carbon, oxygen, and up to iron. These elements are produced through a series of nuclear reactions that occur as the star evolves.
What atoms are heavier than iron?
Atoms heavier than iron are typically produced through processes like nuclear fusion in supernovae or in laboratories. Some examples include atoms like uranium, plutonium, and lead, which have more protons and neutrons in their nuclei compared to iron.
What is heavier iron or silica?
Iron is heavier because iron is a metal and metals are heavier but silica is not a metal so silica is lighter than iron.
Is fusion an endothermic reaction?
It depends on what is being fused. Fusion usually takes place with elements lighter than iron, mostly hydrogen. in those cases it is exothermic. Fusin elements heavier than iron is endothermic.
What is the heviest element that can be made in stars center?
While it is still a star? Iron. Everything heavier must be fused from lighter elements in a supernova explosion, which blows the star apart.
Which is heavier iron filings or seawater?
Iron fillings are heavier.
Is iodine heavier than iron?
No, atomically Iron is a heavier element
