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.

Which nuclear fusion cycle is the next one to begin after helium fusion ends in a massive star?

The next nuclear fusion cycle after helium fusion in a massive star is carbon fusion. This process involves fusing helium nuclei to form carbon. Carbon fusion typically occurs in the core of a massive star after helium fusion is completed.


Why is planet Saturn a planet and not a star?

Saturn was not massive enough to initiate nuclear fusion.


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.


What is the element that forms last in nuclear fusion in stars?

Existing element is product of nuclear fusion, heavy element exist from over fusion and thus create high atomic mass substance. To answer what is the element that is form last in nuclear fusion in star is the same as asking what is the heaviest element occur or found in nature. Base on what is in periodic table. The heaviest element found naturally is around Uranium - Plutonium thus it could be considered the last product known in nuclear fusion in star. There are heavier element than Uranium and Plutonium but those are synthesize element. Nuclear fusion might go to element heavier than what is known in our periodic table but those substance may be unstable and decay over time until none of those exist.


The last two elements that a massive star produces are hydrogen and helium why is this the last reaction?

Hydrogen and helium are the lightest and most abundant elements in the universe. In the core of a massive star undergoing nuclear fusion, hydrogen and helium are fused into heavier elements like carbon, oxygen, and iron. Once the star reaches the stage where it can no longer sustain fusion reactions to produce heavier elements, hydrogen and helium remain as the last elements in its core before it undergoes a supernova explosion.

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.

What is the combining of less massive elements on a star?

Nuclear fusion.

The element that burns as fuel in star?

The energy in stars comes from nuclear fusion. Hydrogen atoms are continually fused together to created helium and with it, massive amounts of energy.

What causes a planet to become a star?

A planet cannot become a star. A star is an object that is massive enough to release energy via nuclear fusion. A planet is much less massive.

Is iron the heaviest element made in abundance in massive stars?

No, iron is not the heaviest element made in massive stars. Massive stars produce elements through nuclear fusion in their cores, creating heavier elements than iron, such as lead, gold, and uranium. Iron is often referred to as the endpoint of nuclear fusion in massive stars because the energy required to fuse iron exceeds the energy output of the reaction.


Is Jupiter close to becoming a star?

Jupiter was going to become a star but when studied closely, scientists found that it was not massive enough to cause nuclear fusion in its core
