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
Why can't massive stars generate energy from iron fusion?
Massive stars cannot generate energy from iron fusion because iron fusion does not release energy, rather it absorbs energy. Iron is the most stable element, and fusion of iron requires more energy than it produces, making it an unfavorable process for generating energy in stars. This leads to the collapse of the star's core and triggers a supernova explosion.
What is the most massive element that can be formed by nuclear fusion with the liberation of energy?
Iron is the most massive element that can be formed by nuclear fusion with the liberation of energy. This is because fusion reactions beyond iron require an input of energy rather than liberating energy.
Nuclear fusion only releases energy when elements that are lighter than what element are involved?
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.
Why is iron significant to understanding how a supernova occurs?
Iron cannot release energy by fusion. When a star has used up all the lighter elements and has just iron left, it has no more nuclear "fuel". That causes the star to contract then explode very violently as a supernova.
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.

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.
Massive stars cannot generate energy through iron fusion because?
No energy is gained when fusing iron into heavier elements. Heavier elements have a higher potential energy (nuclear energy) than iron.
Why can't massive stars generate energy from iron fusion?
Massive stars cannot generate energy from iron fusion because iron fusion does not release energy, rather it absorbs energy. Iron is the most stable element, and fusion of iron requires more energy than it produces, making it an unfavorable process for generating energy in stars. This leads to the collapse of the star's core and triggers a supernova explosion.
When fusion occurs it creates what?
iron
Would you still have to remove the fusion monsters as a result of fusion gate if you have imperial iron wall?
If Imperial Iron Wall is in play you can't activate the effect of fusion gate at all.
What is the most massive element that can be formed by nuclear fusion with the liberation of energy?
Iron is the most massive element that can be formed by nuclear fusion with the liberation of energy. This is because fusion reactions beyond iron require an input of energy rather than liberating energy.
What metal causes the death of red giant?
The heaviest element that can be produced in the core of a massive star before it goes supernova is iron. Iron does not cause the death of a red giant, but rather the inability to continue nuclear fusion in its core, leading to its collapse and eventual explosion as a supernova.
Does nuclear fusion create thermal energy?
Yes, fusion is exothermic until nickel & iron are produced.
Nuclear fusion only releases energy when elements that are lighter than what element are involved?
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.
