Fusion reactions can occur inside stars for two reasons...
- The temperature is extremely high, resulting in full ionization of the electrons from the hydrogen atoms. This removes one of the barriers from the fusion process that would interfere due to the electromagnetic force.
- The pressure is also extremely high, high enough to overcome the repulsion of the protons in the hydrogen atoms also due to the electromagnetic force, allowing the hydrogen atoms to fuse into helium atoms. The weak interaction then causes two of the protons to change into neutrons, completing the change into helium.
Both of these conditions are initiated by gravity.
What else can I help you with?
When nuclear fusion occurs what form of radiation is released from the star?
Positrons and neutrinos are released by nuclear fusion.
What is the nuclear fusion order in a star?
In a star, nuclear fusion occurs in multiple stages. The main sequence stars, like our sun, primarily fuse hydrogen into helium in their cores through the proton-proton chain reaction. As the star evolves, it can go on to fuse heavier elements like carbon, oxygen, and eventually iron through various nuclear reactions.
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.
What is the nuclear fusion order for a star?
The nuclear fusion order for a star like our Sun involves the conversion of hydrogen into helium. This fusion process occurs in multiple stages, beginning with the fusion of hydrogen isotopes (protons) into deuterium, and then further reactions combine deuterium to form helium-3 and, ultimately, helium-4.
Does nuclear fusion occur in stars?
Nuclear fusion takes place only in the core of the Sun, or any star. Extremely high energy (temperatures) are required to force atomic nuclei together. The fusion reaction releases heat energy, which continues the fusion of other nuclei.
What kind of reaction occurs to produce energy inside a star?
Nuclear Fusion
What energy would be used in a nuclear reaction in a star?
Nuclear fusion.
When nuclear fusion occurs what form of radiation is released from the star?
Positrons and neutrinos are released by nuclear fusion.
What chemical reaction produces heat and energy in a star?
it is not a chemical reaction. It is a nuclear reaction and it is called fusion.

What creates the heat and light in a star?
Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.
What is the name of the reaction tat occurs in the core of a star that makes the star hotter and luminescent?
Nuclear fusion, when hydrogen under extreme heat and pressure will fuse into helium and release a tiny bit of energy.
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.
What is the name of the nection that occurs in the core of a star that makes it hot and luminescent?
Stars are powered by nuclear fusion, in which atoms of hydrogen are fused into atoms of helium, releasing a little energy with each reaction.

How is nuclear fusion in a main-sequence star is different from nuclear fusion in a giant star.?
Nuclear Fusion in a Giant Star involves Helium being fused into a hydrogen shell that surrounds the core, and Nuclear Fusion in a Main-Sequence star involves Hydrogen being fused into Helium to produce Energy inside of the core.
