What else can I help you with?
The final core element for a massive star is?
The final core element for a massive star is iron. When a massive star exhausts its nuclear fuel, iron builds up in its core due to fusion reactions. Iron cannot undergo further fusion to release energy, leading to a collapse and subsequent supernova explosion.
Can iron undergo fusion in any star?
No. Only the most massive stars can fuse iron.
What is the heaviest element that a star can produce through fusion before going supernova?
The heaviest element that can be produced prior to supernova is Iron (Fe).
What is the last element to be formed in a very large star as it contracts from the red giant stage?
The last element to be formed in a very large star during its contraction from the red giant stage is iron. As the star's core becomes increasingly hot and dense, nuclear fusion processes create heavier elements up to iron. However, fusion of iron does not release energy, leading to a halt in the fusion process and eventually resulting in the star's collapse and supernova explosion.
What force is responsible for crushing or collapsing stars?
A supernova is caused the the fusion of (in most cases helium) molecules in iron. Once you reach iron, you can't use fusion. Thus, the star can't produce the energy to keep it stable and gravity causes it to collapse.
Why can iron fusion not support a star because of iron?
Iron fusion cannot support a star because iron is the most stable element and cannot release energy through fusion reactions. This causes the star to collapse, leading to a supernova explosion.
The onset of iron fusion causes a star to become a?
The onset of iron fusion causes a star to become a supernova. This process occurs when the star's core collapses due to the inability to support the fusion of iron, leading to a catastrophic explosion.
Why can the fusion of iron into heavier elements not support a star?
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.
What element is produced by fusion in the star before a super nova occurs?
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.
A massive star with what element does nuclear fusion stop?
A massive star with iron in its core will stop nuclear fusion, leading to its collapse and eventual explosion as a supernova. Iron is the element at which fusion becomes endothermic, meaning energy is no longer released in the process.
The final core element for a massive star is?
The final core element for a massive star is iron. When a massive star exhausts its nuclear fuel, iron builds up in its core due to fusion reactions. Iron cannot undergo further fusion to release energy, leading to a collapse and subsequent supernova explosion.
Is iron compound mixture elements?
Iron is an element, and is the heaviest element that may be made by fusion in a Star such as our Sun.
Is iron a compound mixture element?
Iron is an element, and is the heaviest element that may be made by fusion in a Star such as our Sun.
In stars more massive than the Sun fusion continues until the core is almost all?
Iron. Iron is the heaviest element that can be produced through nuclear fusion in a star, and once the core of a massive star is mostly composed of iron, it can no longer sustain fusion reactions. This triggers its collapse and ultimately leads to a supernova explosion.
Can iron undergo fusion in any star?
No. Only the most massive stars can fuse iron.
What is the heaviest element that a star can produce through fusion before going supernova?
The heaviest element that can be produced prior to supernova is Iron (Fe).
