Why are all elements heavier then iron created during a supernova?
The rapid collapse of the star compresses atoms together and may cause nuclear fusion and make heavier elements.
Why are lighter elements used in fusion reactions?
Because their binding energy is greater than that of their products, thus permitting an energy release. This is the same reason heavier elements are used in fission reactions. The range of elements from iron to lead has the lowest binding energy.
How do you find elements of nuclear fusion?
In nuclear fusion, elements are created by combining two lighter atomic nuclei to form a heavier nucleus. This process releases a large amount of energy. Elements found in nuclear fusion reactions typically include hydrogen isotopes like deuterium and tritium.
How are elements larger than 10 protons made?
Elements larger than 10 protons are primarily formed through nuclear fusion in stars, where lighter elements combine under extreme temperature and pressure. In massive stars, fusion processes can create heavier elements up to iron through successive fusion reactions. Elements heavier than iron are typically produced in supernova explosions or neutron star mergers, where the intense energy allows for rapid neutron capture processes (r-process) and other nuclear reactions to occur. These processes contribute to the cosmic abundance of heavier elements in the universe.
What kind of reactions provide a star with energy?
Stars obtain energy from a reaction called nuclear fusion. Nuclear fusion causes lighter elements to become heavier elements. The most common reaction fuses hydrogen into helium. But helium can fuse further, to even heavier elements. This releases energy until you reach the element iron. Anything heavier than iron consumes energy, rather than releasing it, when it is formed by nuclear fusion.thermonuclear fusion

Why do heavier elements form at the centre of the sun?
Nuclear Fusion Processes, those that form new elements, require both high temperatures and pressures. These are only found at or near the center of the star. Hydrogen fusion is the easiest (excepting deuterium but that's a bit too detailed for here) and takes place in the smallest of stars. (Brown Dwarves don't count as no fusion is going on there). For successively heavier fusion reactions creating heavier elements higher temperatures and pressures are required and therefore take place nearer the center of the star within the sphere of hydrogen fusion. The very largest star therefore have an onion like structure where more and more internal layer are forming heavier and heavier elements. The heaviest element that can be formed by energy producing reactions is Iron. After that the formation of even heavier elements absorbs energy. This is why all the elements above Iron are thought to form in Super-novas reactions where there is incredible temperatures and pressures and no worry that energy absorbing reactions are going to shut things down.
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.

How are heavier elements formed from hydrogen within the core of a star?
Heavier elements are formed through nuclear fusion processes that take place in the core of a star. Hydrogen atoms undergo fusion to form helium, and then this process continues to create heavier elements by fusing helium atoms together. As the star fuses lighter elements, it produces heavier elements through a series of nuclear reactions.
What kind of reaction does oxygen undergo fusion or fission?
Oxygen undergoes fusion reactions in the cores of massive stars, where it can fuse into heavier elements. Oxygen does not undergo fission reactions naturally.
Why can elements be produced in the sun but not in the earth atmosphere?
Over time, the fusion reactions can form as the reactions that form nuclei of slightly heavier elements, such as carbon, nitrogen, and oxygen. Thank you = )

How are the elements carbon nitrogen and oxygen produced in stars like the sun?
These fusion (carbon , nitrogen , and oxygen) reactions form nuclei of sightly heavier elements.
Who makes arsenic?
Arsenic is an element. It is made (like all elements heavier than helium) by fusion reactions inside stars.
Did gravity pulled the atoms together to form heavier elements?
Yes, gravity plays a role in pulling atoms together in stars to form heavier elements through nuclear fusion. In the intense pressure and temperature conditions of a star's core, lighter elements like hydrogen fuse together to form heavier elements like helium, carbon, and oxygen.
