This question relates to nuclear fusion.
Nuclear fusion (which should not be confused with nuclear fission) is a process in which atoms are combined to produce a new atom. This is a very different thing from a simple chemical reaction, and has a lot more energy involved.
For example, two hydrogen atoms can be combined to produce a helium atom, and when this happens, a very great amount of heat is released. Helium atoms can also be fused. In fact, every atom we have either is hydrogen, or was built by processes involving fusion at some point, in stars of long ago.
Part of the problem with this is that it takes a lot of heat and pressure to make hydrogen atoms fuse into helium. It is easy for a star, which has a lot of pressure and heat inside. But on Earth, doing it the same way would take more pressure than any physical container can hold at a temperature that would vaporize anything we can make things out of. And to make things even more difficult, we have to be able to put fuel in, and have to get more energy out than it takes to run the operation, which is difficult in this case.
But scientists are working on it. People are trying to build containment out of magnetic fields. There are other types of attempts also.
Helium cannot be turned into hydrogen to produce energy. Helium and hydrogen are two different elements with different atomic structures and properties. However, fusion reactions involving hydrogen isotopes such as deuterium and tritium can produce energy in a process known as nuclear fusion.
In nuclear fusion, atoms of hydrogen isotopes such as deuterium and tritium are used to produce helium atoms with larger masses. The fusion reaction involves the combination of these hydrogen isotopes to form helium, releasing a significant amount of energy in the process.
The sun produces energy through nuclear fusion, specifically hydrogen fusion in its core. In this process, hydrogen nuclei combine to form helium, releasing a large amount of energy in the form of light and heat.
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.
The nuclear reaction that combines hydrogen to form helium and produces most of the sun's energy is called nuclear fusion. In this reaction, hydrogen nuclei (protons) fuse together to form helium nuclei, releasing a large amount of energy in the form of light and heat.
Helium cannot be turned into hydrogen to produce energy. Helium and hydrogen are two different elements with different atomic structures and properties. However, fusion reactions involving hydrogen isotopes such as deuterium and tritium can produce energy in a process known as nuclear fusion.
Helium atoms
By thermonuclear fusion of hydrogen into helium.
Both Hydrogen and helium to produce energy
Stars produce energy from the fusion of hydrogen into helium during the main sequence stage of their life cycle. This is when a star is stable and balanced, and the fusion of hydrogen into helium in its core generates the energy that makes the star shine.
fusion reaction of helium and hydrogen
The sun consumes hydrogen nuclei in its core through a process called nuclear fusion to produce energy and helium. This fusion process releases an immense amount of energy in the form of light and heat.
Stars produce energy by fusing hydrogen into helium through a process called nuclear fusion. This fusion reaction releases a tremendous amount of energy in the form of light and heat, which powers the star and allows it to shine.
The conversion of Hydrogen into Helium (nuclear fusion).
main sequence
The sun's energy (and that of all other stars) comes from nuclear fusion. The nuclei of hydrogen atoms (ie protons) fuse together to produce helium and release energy.
The sun fuses hydrogen atoms to produce helium atoms in its core through a process called nuclear fusion. This process generates a tremendous amount of energy in the form of light and heat, which sustains life on Earth.
