The fusion of iron into heavier elements cannot support a star because it requires more energy than it produces, leading to a loss of energy and the collapse of the star.
When heavier elements undergo fusion, they release energy in the form of light and heat. This process can only occur in extreme conditions, such as the high temperatures and pressures found in stars or during a thermonuclear reaction. Fusion of heavier elements can lead to the formation of even heavier elements and can release a tremendous amount of energy.
Iron fusion in stars plays a crucial role in the formation of heavier elements in the universe through a process called nucleosynthesis. When a star fuses iron atoms in its core, it releases energy but cannot produce more energy by fusing iron. This leads to the collapse of the star, triggering a supernova explosion. During the explosion, the intense heat and pressure allow for the fusion of heavier elements beyond iron, such as gold, silver, and uranium. These newly formed elements are then scattered into space, enriching the universe with a variety of elements essential for the formation of planets, stars, and life.
Elements heavier than iron are formed through processes like supernova explosions, where the intense heat and pressure create conditions for nuclear fusion to occur, leading to the synthesis of heavier elements. This process is known as nucleosynthesis and is crucial for the creation of elements like gold, uranium, and beyond in the universe.
In a supernova event, elements such as hydrogen, helium, carbon, oxygen, and heavier elements like iron are produced through nuclear fusion and nucleosynthesis processes.
Elements more massive than iron are created through processes such as supernova explosions and neutron star mergers, where extreme conditions allow for the fusion of lighter elements into heavier ones.
Iron
The rapid collapse of the star compresses atoms together and may cause nuclear fusion and make heavier elements.

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.
When heavier elements undergo fusion, they release energy in the form of light and heat. This process can only occur in extreme conditions, such as the high temperatures and pressures found in stars or during a thermonuclear reaction. Fusion of heavier elements can lead to the formation of even heavier elements and can release a tremendous amount of energy.
Nuclear fusion only releases energy when elements lighter than iron are involved. This is because elements lighter than iron release energy due to the process of fusion, while elements heavier than iron require energy to be input for fusion to occur.
Heavier elements are formed from hydrogen, the most abundant element in the universe, through a process called nuclear fusion. There are machines or structures in the universe that do this, and we call them stars. It is the process within stars, stellar nucleosynthesis, that allows heavier elements to be created up through iron. Elements heavier than iron are formed in supernova events.

Heavier atoms which could not be formed as a result of fusion are produced as the result of a star that has run out of fuel exploding. It essentially forces atoms which do not release energy to fuse together.
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
Before a supernova occurs, a massive star undergoes fusion to produce iron in its core. As fusion progresses, the star creates heavier elements up to iron, which cannot release energy through fusion. When the core becomes predominantly iron, it can no longer support the star against gravitational collapse, leading to a supernova explosion.
No energy is gained when fusing iron into heavier elements. Heavier elements have a higher potential energy (nuclear energy) than iron.
