None. Hydrogen and Helium are base elements.
Helium is helium.
Chemically yes, but with Nuclear Physics in stars:
- H + H --> D + e+ + v + 0.42 MeV, H + H --> D + e+ + v + 0.42 MeV, D + D --> He3 + n + 3.27 MeV (50%)
- H + H --> D + e+ + v + 0.42 MeV, H + H --> D + e+ + v + 0.42 MeV, D + D --> He3 + H + 4.03 MeV (50%)
- H + H --> D + e+ + v + 0.42 MeV, H + D --> He3 + gamma photon + 5.49 MeV, H + H --> D + e+ + v + 0.42 MeV, H + D --> He3 + gamma photon + 5.49 MeV, He3 + He3 --> He + H + H + 12.86 MeV (100%)
- H + D --> He3 + gamma photon + 5.49 MeV (100%)
- D + D --> He3 + n + 3.27 MeV (50%)
- D + D --> He3 + H + 4.03 MeV (50%)
- D + T --> He + n + 17.59 MeV (100%)
- T + T --> He + n + n + 11.33 MeV (100%)
Four or two, depending on the kind of hydrogen isotope you are burning. As you can see in the equations above burning four ordinary atoms of hydrogen to ordinary helium is a complicated and slow process compared to burning two atoms of various isotopes of hydrogen, however a star has such tiny quantities of deuterium and tritium that depending on them for fusion helps little.
What else can I help you with?
What elements are found in stars in the beginning of their life?
Mostly lighter elements, such as hydrogen (one proton) and helium (two protons). The helium found in young stars comes from nuclear fusion reactions where 2 hydrogens fuse to make a helium atom.
How do most stars make light?
Well Stars use 4 atoms of Hydrogen and 1 atom of Helium fuse together.
What nuclear process coverts helium and hydrogen gases from lighter to heavier elements?
The process is called fusion; hydrogen nuclei are fused together to make helium. At much higher temperatures and pressures, the helium can fuse into carbon and nitrogen and oxygen.
What chemical is inside the sun?
Hydrogen is in the sun, when the hydrogen atoms fuse (join together) they make helium in stars. this gives out lots of heat and light.
What does the sun run on?
Hydrogen. The temperatures and pressures are big enough for these atoms to collide or fuse together to make helium. This "nuclear fusion" give of loads of energy.
Is helium naturally produced in stars?
Yes, stars fuse Hydrogen atoms to make Helium in a natural process.
What element do you get if you fuse two helium nuclei together?
Nuclear fusion occurs when two nuclei fuse together. This is frequently nuclei of deuterium and tritium (both hydrogen isotopes), which form a helium nucleus plus a neutron.
What is created when two hydrogen atoms fused together?
Hydrogen atoms have one proton in their nuclei. When two hydrogen atoms fuse together they make one helium atom that contains two protons in its nucleus. This is called nuclear fusion, which powers the stars in the universe.
What does the sun burn to make something else?
The sun "burns" hydrogen to make helium. At 10 million degrees Kelvin, hydrogen begins to fuse into helium. In other, larger stars all the hydrogen will fuse to become helium, then all the helium will fuse to become beryllium, all the beryllium will fuse to become carbon, and so on, until it reaches iron. Fusion no longer produces energy after iron, so the star either collapses or goes supernova. "Burning" is not the correct term, fusion is.
How many helium nuclei lumped together make carbon?
3
Where does the sun get its energy to heat the earth?
by nuclear fission happening in its core the hydrogen fuses together to make helium and light when thousands of particles fuse at the same time you get very bright light (the sun!)
Tiny particles of hydrogen fuses to helium in the sun?
Yes, they do. Because of the enormous gravity of the sun Hydrogen atoms fuse to each other (only 2) to make Helium.
