Hydrogen-1 is fused into helium-4. This happens at high temperatures - somewhere around 14 million kelvin (which, at such high temperatures, is the same as 14 million degrees Celsius, for all practical purposes). There are two main reaction chains that in stars: the proton-proton chain reaction, and the CNO cycle. I suggest you read the corresponding Wikipedia articles, if you want more details about each of the reaction chains. Anyway, in our Sun, the predominant reaction chain is the proton-proton chain reaction.
What else can I help you with?
What type of energy is the sun's energy source?
hydrogen fusion
Is oxygen the fusion in the interior of the sun?
No, it is hydrogen that is the fuel for fusion in the sun
How is the sun heated?
fusion of hydrogen
What is the role of hydrogen gas in the sun?
The hydrogen in the Sun is fuel for the nuclear fusion reaction.
What is the sun's source of enegry?
The Sun's energy is generated by nuclear fusion, the fusion of hydrogen into helium in the core of the Sun.
What does the fusion of hydrogen nuclei in sun produce?
The fusion of hydrogen nuclei in the sun produces helium, along with energy in the form of light and heat. This process is known as nuclear fusion and is the source of the sun's energy.
How does the nuclear fusion generate energy?
The Sun energy is from hydrogen fusion.
What makes sun?
Nuclear fusion of hydrogen.
What is the order in which elements undergo fusion on the sun?
In the core of the Sun, hydrogen atoms fuse to form helium in a process known as hydrogen fusion. This is the primary fusion process occurring in the Sun. As the core hydrogen is depleted, helium fusion into heavier elements like carbon and oxygen will occur in later stages of the Sun's evolution.
When does hydrogen-helium fusion and helium-carbon fusion occur in stars like our sun?
When hydrogen stocks run out
Why sun have hydrogen and helium?
Hydrogen is the fuel used by the sun, helium is the waste produced by hydrogen use in the fusion process
What element is produced by fusion in the interior of sun?
Helium is produced by fusion in the interior of the Sun.
