How many atoms of hydrogen are needed to create 1 atom of helium?

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.

But carbon is formed from helium in giant stars following a very complicate system of nuclear reactions.

What fusion in stars occurs to create the element helium?
Hydrogen undergoes nuclear fusion in the core of the sun to form helium.
How many hydrogen atoms that fuse to form a helium is?
two hydrogen atoms
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
Are hydrogen or oxygen atoms used to produce helium atoms with larger masses in nuclear fusion?
Hydrogen.
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?
the number of helium and hydrogen atoms is the same
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.
What atoms do the sun produce by fusing hydrogen atoms?
The sun produces energy by fusing hydrogen atoms into helium atoms. This is a nuclear fusion that occurs at the sun's core.
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
Is the ratio of the amount of hydrogen and helium in the sun increasing or decreasing?
Since hydrogen atoms in the sun are fused into helium atoms, the amount of helium is increasing and the amount of hydrogen is decreasing.
What fusion in stars occurs to create the element helium?
Hydrogen undergoes nuclear fusion in the core of the sun to form helium.
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.
How many hydrogen atoms that fuse to form a helium is?
two hydrogen atoms
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 !
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.
In stars energy is produced as primarily hydrogen atoms are combined to form?
helium atoms
