What are the fuels that stars use to create energy through fusion toward the end of their lives if they are a more massive star?
Toward the end of their lives, more massive stars undergo a series of fusion processes, starting with hydrogen and progressing to helium, carbon, and oxygen. As they evolve, they can fuse heavier elements, such as neon, magnesium, and eventually iron. However, iron fusion does not release energy, leading to the star's eventual collapse and explosion as a supernova. This process results in the synthesis of even heavier elements, which are dispersed into space.

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 difference of a star and a planet?
A star is a luminous ball of plasma held together by its own gravity and produce energy through thermonuclear fusion. A planet is a body orbiting a star massive enough to be rounded by its own gravity but not massive enough to conduct 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.
How do stars like the sun create energy that is later radiated away into space?
Stars like the sun create energy through nuclear fusion in their cores. This process involves the fusion of hydrogen atoms to form helium, releasing a tremendous amount of energy in the form of light and heat. This energy is then radiated away from the star into space.
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.
What process does the sun go through to create energy?
Fusion
What does nuclear fusion produce?
It combines atoms to create new and more massive elements and releases a great deal of energy.
How do star use energy?
Stars fuse hydrogen through nuclear fusion into helium and release the massive resulting energy into space.
Is the sun dry?
The sun is not dry, as it is a massive ball of hot plasma that emits energy through nuclear fusion.
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.
Does nuclear fusion in massive stars create heavy elements?
yes
What difference of a star and a planet?
A star is a luminous ball of plasma held together by its own gravity and produce energy through thermonuclear fusion. A planet is a body orbiting a star massive enough to be rounded by its own gravity but not massive enough to conduct fusion.
What is main disadvantage of fusion?
It requires almost as much energy to create nuclear fusion as the energy it creates. :)
What are the names of the elements used to create the light in a star?
Hydrogen and helium are the main elements used to create light in stars through the process of nuclear fusion in their cores. These elements undergo fusion reactions to produce energy, which is emitted as light and heat.
How does a star create such energy?
nuclear fusion
What elements the sun fusion to create energy?
BUT
