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.

What fusion in stars occurs to create the element helium?
Hydrogen fusion occurs in stars to create helium. This process, known as nuclear fusion, involves the fusion of hydrogen nuclei to form helium nuclei, releasing large amounts of energy in the process.
What is the process of joining two nuclei together to form a new element called?
The process of joining two nuclei together to form a new element is called nuclear fusion. This occurs when the nuclei of two atoms are forced together, typically at very high temperatures and pressures, overcoming their electrostatic repulsion to merge and form a heavier nucleus. Nuclear fusion is the process that powers the sun and other stars.
What layer of the sun does fusion occur?
Nuclear fusion occurs in the solar core.
When the atomic nuclei of hydrogen and lithium are squashed together what is the element produced?
When the atomic nuclei of hydrogen (specifically, hydrogen isotopes like deuterium or tritium) and lithium are fused together under extreme conditions, they can produce helium. This process occurs in stellar environments, such as in stars where fusion reactions take place. Additionally, the fusion of lithium with hydrogen can also produce isotopes of helium, along with other particles like neutrons.
When the cloud contracts and powerful reactions start to turn hydrogen atoms into helium atoms to produce?
This process is known as nuclear fusion, which occurs in the core of a star like our sun. The energy produced from this fusion process powers the star and creates light and heat. It is a key process in maintaining the balance between the force of gravity pulling inward and the energy generated by the fusion reactions pushing outward.
What is produced when fusion occurs in the sun?
Heat and helium mainly
What is Alternative energy source produced from atomic reactions?
Nuclear fission is when a neutron is fired at an element with a high atomic number, which splits and releases more neutrons and energy as a result. Nuclear fusion occurs in stars and experimental reactors.
What layer of the sun does nuclear fusion occur?
It has to be at hundreds of millions of degrees kelvin, before a fusion reaction between deuterium and tritium will start
What fusion in stars occurs to create the element helium?
Hydrogen fusion occurs in stars to create helium. This process, known as nuclear fusion, involves the fusion of hydrogen nuclei to form helium nuclei, releasing large amounts of energy in the process.
What element is the fuel for main-sequence star?
Stars a giant balls of gas mainly hydrogen and helium. inside a star there are such temperatures that hydrogen fusion occurs making helium and when the star runs outta hydrogen it gets hotter and helium fusion occurs then carbon fusion etc etc. so ultimately it depends on the age of the star.
Does fission or fusion occur in the sun?
Fusion occurs in the sun.
Does fusion or fission occur in the sun?
Fusion occurs in the sun.
Central part of the sun where fusion occurs?
Central part of the Sun where nuclear fusion occurs is called core.
What is the process of joining two nuclei together to form a new element called?
The process of joining two nuclei together to form a new element is called nuclear fusion. This occurs when the nuclei of two atoms are forced together, typically at very high temperatures and pressures, overcoming their electrostatic repulsion to merge and form a heavier nucleus. Nuclear fusion is the process that powers the sun and other stars.
Where does the fusion reacion occur on the sun?
Fusion occurs in the core of the Sun
What element is formed when the hydrogen bomb explodes?
When a hydrogen bomb explodes, the primary element formed is helium. This occurs through the process of nuclear fusion, where hydrogen isotopes combine to form helium atoms, releasing a large amount of energy in the process.
When fusion occurs it creates what?
iron
