Well we all SHOULD know that elements from Manganese down to Hydrogen combine to create energy and all elements from Cobalt up decompose to create energy. All this ends at Iron. So how does Iron create nuclear energy? Does it combine or does it decompose?
Hi. Iron is the ultimate byproduct of fusion. When a stars core gets to the point where there are not enough fusionable elements to keep fighting gravitational collapse then gravity's energy forces some of the iron to form even higher order elements. These mostly radioactive elements under go fission, but they are really converting the gravitational kinetic energy, not producing energy. Hope this helps.
Iron does not naturally undergo nuclear fusion even in stars. Actually, when stars have too much iron, they die because they cannot use iron as more fuel. Because iron does not undergo fusion naturally, it doesn't yield nuclear energy.
Where fusion is the combining of the nuclei of smaller elements to release energy, and fission is the splitting of larger elements to release energy, it is not decomposition of larger elements and and it is not just combining of smaller ones. And we can not create .energy. It is thought that the center of the earth is composed of molten iron and the core is kept warm by radioactive decay, but I do not know what you are asking about iron. There are radioactive isotopes, and they have used it in fusion reactions.
