Four. There are a couple of possible routes to the fusion reaction that makes helium-4 as a finished product, but it's all about the hydrogen. Most hydrogen is just one proton. Helium-4 has two protons and two neutrons. It takes two hydrogen atoms to contribute their two protons to the nucleus of our He-4 atom. And it takes two more hydrogen atoms (the protons) to undergo transformation into two neutrons to complete the assembly. Note that atoms do not exist as such anywhere on or in the sun. The temperatures are far too high for any electrons to be hanging around any nuclei; our star is a ball of plasma. Our friends at Wikipedia have a nice article posted on proton-proton fusion. A link is provided.
What else can I help you with?
What happens to hydrogen at very high temperatures?
They are fused into helium and create energy. But it takes 4 hydrogen atoms to make 1 atom of helium. The Hydrogen is first converted to Deuterium (heavy hydrogen), and the two deuterium atoms fuse to make the Helium atom. This process releases a lot of energy, not the least because of the neutrons released. Lol
What fusion in stars occurs to create the element helium?
Hydrogen fusion occurs in stars to create helium. This process, known as nuclear fusion, involves the fusion of hydrogen nuclei to form helium nuclei, releasing large amounts of energy in the process.
Are hydrogen or oxygen atoms used to produce helium atoms with larger masses in nuclear fusion?
Hydrogen atoms are used to produce helium atoms with larger masses in nuclear fusion. During the fusion process, hydrogen isotopes (such as deuterium and tritium) combine to form helium, releasing vast amounts of energy in the process. Oxygen atoms are not typically involved in nuclear fusion reactions to produce helium.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
What heavier element is created when hydrogen atoms fuse together in the suns core?
Normal "main sequence" stars fuse hydrogen into helium during most of the star's life. The core of a star gets so hot that the hydrogen atoms begin to fuse together. As hydrogen only has 1 proton when if fuses with another hydrogen atom it has 2 protons so has become helium.
Source of the suns energy?
Elements used to create: Hydrogen, Helium, Time. Things the Sun contains: Neutrinos, Heat, Atoms, Photons, Hydrogen, Helium.
What is the main source of the sun?
If source you mean, fuel...then the answer is Hydrogen gas. The sun fuses to hydrogen atoms to create helium.
The sun fuses hydrogen atoms into what?
Hydrogen atoms fuse into helium.
How many atoms of hydrogen are need to create 1 atom of helium?
2, but its an isotope of hydrogen with a mass of 2 rather then 1.09
What is the main source of energy in star like sun?
Hydrogen fusion is the main energy source in any star.Put very simply, four Hydrogen atoms fuse to create Helium. The atomic weight of Helium is slightly less than four Hydrogen atoms the extra mass is released as energy.
What element is created when hydrogen atoms fuse together in the sun and core?
When hydrogen atoms fuse together in the sun's core, they create helium. This process releases energy in the form of light and heat, which provides the sun's power.
Which has the least number of atoms 5g of hydrogen or 10g of helium?
10g of helium has fewer atoms. This is because the atomic mass of helium is much higher than that of hydrogen, so the same mass of helium contains fewer atoms than the same mass of hydrogen.
Do Hydrogen and helium atoms make up fifty percent of atoms in outer space?
Hydrogen and helium make about 98% of the atoms in the solar system !
In stars energy is produced as primarily hydrogen atoms are combined to form?
helium atoms
What kind of atom is fused with hydrogen to create energy on your sun?
Hydrogen: the mutual fusing of H atoms into Helium, with consequent release of energy.
What happens to hydrogen at very high temperatures?
They are fused into helium and create energy. But it takes 4 hydrogen atoms to make 1 atom of helium. The Hydrogen is first converted to Deuterium (heavy hydrogen), and the two deuterium atoms fuse to make the Helium atom. This process releases a lot of energy, not the least because of the neutrons released. Lol
What atoms do the sun produce by fusing hydrogen atoms?
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.
