What happens when two nuclei that are heavier than iron are fused?

The two nuclei's are lighter than iron then when they are fused together they will release energy.
If the two nuclei's are heavier than iron they will absorb energy when fused.

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
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.
Is iodine heavier than iron?
No, atomically Iron is a heavier element
Which is heavier lead or iron?
Lead is heavier than iron.
What happens during nuclear fusion and fission?
A (small) amount of mass is "converted" into energy. If you fuse light elements into heavier ones (particulally hydrogen into helium), you end up with less mass than you started with. Likewise breaking apart heavy elements into lighter ones result in a "loss" of mass. Note - iron is the low point of all of this, thus you can fuse up to iron OR fission down to iron - but no farther.
How are elements with nuclei larger than iron nuclei formed?
Supernova form heavier elements

How light elements and heavy elements formed differently?
The formation of the elements is a nuclear process that usually happens in stars. The core of the star is hot enough and has enough pressure to overcome the electric repulsion of the atomic nuclei and literally fuse the nuclei together. This process happens over and over again, but seems to stop at a certain mass. It appears that elements heavier than iron cannot be formed in the core of a star. These elements require more extreme conditions. The heavier elements on the Periodic Table (after Fe) are formed in supernova. These nuclei require tremendous energy to form, this energy must come from an event as large as a supernova.
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.
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.
Which is heavier iron filings or seawater?
Iron fillings are heavier.
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.
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.
Is iodine heavier than iron?
No, atomically Iron is a heavier element
Which is heavier lead or iron?
Lead is heavier than iron.
