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.
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
What nuclear process occurred when light elements combine to form heavier elements?
Nuclear Fusion
How are elements with atomic masses greater than uranium made?
Elements that have greater atomic masses then uranium are created using nuclear fission.

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.
Why can elements be produced in the sun but not in Earth's 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 = )

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.
Who makes arsenic?
Arsenic is an element. It is made (like all elements heavier than helium) by fusion reactions inside stars.

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.
