When hydrogen fuses into helium protons break away. During the process, energy is released.
The sun fuses hydrogen to make helium. It will be several billion years before the sun fuses helium to make heavier elements.
A "red giant" star can fuse both hydrogen (in the star's outer shells) and helium (in the core).
It definitely runs on hydrogen, and its made of helium, as well. --- Yes, it is mainly made of hydrogen which it uses as a fuel. It fuses hydrogen nuclei together to form helium, producing huge amounts of energy through this nuclear fusion reaction. Helium is produced by this reaction. The most important fusion reaction is stars the size of our Sun, is the so called 'Proton - proton' reaction, which in summary, combines 4 nuclei of Hydrogen to produce one nucleus of Helium, plus two nuclei of Hydrogen, and positrons and gamma rays. Gamma rays get transformed inside the sun into less harmful electromagnetic radiations. There are other fusion reaction inside stars, which combine lighter atom nuclei into heavier nuclei, going up to producing carbon C and iron Fe nuclei.
If you are asking "how helium formed the sun?" then for your information, sun and all the stars are formed mostly from Hydrogen. And if you are asking "How helium is formed in the sun?", the answer is that the Hydrogen in the sun fuses in itself(that's where from the sun get's its energy and luminosity) producing variety of elements like helium, carbon oxygen,iron etc.
A red dwarf fuses hydrogen into helium, just like any star, albeit at a very conservative rate.
When hydrogen fuses into helium protons break away. During the process, energy is released.
an isotope of hydrogen that has a mass of 2 rather then 1.09 fuses to make helium
helium
Helium exists because Hydrogen fuses into Helium in the core of hot stars.
Very high temperatures and pressures are needed to fuse hydrogen into helium.
Hydrogen atoms fuse into helium.
No. It is the other way around. Hydrogen nuclei fuses to form helium in the center of the sun.
When hydrogen is fused in the suns core Helium is produced.
The sun fuses hydrogen to make helium. It will be several billion years before the sun fuses helium to make heavier elements.
The sun fuses hydrogen into helium. The mass of the resulting helium is not the same as the original hydrogen. The difference is energy.
Our sun mostly transforms hydrogen nuclei into helium by fusion, but it also fuses helium with helium, lithium with hydrogen, and beryllium with hydrogen, to make elements as heavy as boron.
