Do stars give off light as a part of a nuclear fusion reaction in which helium atoms are split into hydrogen atoms?

No. In a fusion reaction, a heavier element is made of a lighter pair by "gluing" them together in a fusion reaction. When we split an atom, that's called atom splitting, or sometimes fission, not fusion. They are opposites. Stars give off light, but the primary fuel in their fusion engines is hydrogen, which they convert into helium. As the hydrogen burns out, the star begins making helium into carbon.

In stars hydrogen nuclei combine with each other to form helium and other heavier elements. What is this process called?
This process is called "nuclear fusion".
What is the main activity of a sequence star?
The activity is -fusing hydrogen into 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.
What were the two chemicals in the big bang?
Well, if you believe in such things, the Big Bang was only a mass Hydrogen, which exploded due to massive internal forces. Hydrogen then fused into all atoms in the universe today through the process of nuclear fusion, which is the same process as that occurs in the center of our sun, and in the hydrogen bomb. Nuclear fusion is not utilized in nuclear power plants, as the only sustainable level of nuclear fusion is to large to be contained. Essentially, it would melt everybody who tried to go near a fusion power plant. Nuclear physicist are constantly working on the theoretical process of "cold fusion", but have made very little advancement. It looks like this force may just be for stars bombs and universe making theories ;).
What kind of power is generated in stars?
Nuclear fusion is the process that provides energy to the stars.The star fuses hydrogen to form helium this is a process that gives out a lot of energy,stars which are more passive than our sun then it fuses the helium atoms to form carbon.
What nuclear reaction happens between hydrogen and helium in the sun?
Nuclear fusion, in which hydrogen-1 is fused into helium-4.
How is helium formed from hydrogen?
It's called the proton-proton cycle. It's the source of the sun's energy. Also called nuclear fusion.
Nuclear reaction in the sun's interior convert?
Nuclear fusion converts hydrogen to helium
What is the nuclear process that converts helium and hydrogen from lighter to heavier elements?
Nuclear fusion reaction
Nuclear reaction taking place inside sun is called?
Nuclear fusion; hydrogen into helium.
What type of gas combines to form helium?
hydrogen combine to form helium by nuclear fusion reaction
What type of energy is the sun's energy source?
hydrogen fusion
What primary atomic reaction occurs within the sun that converts hydrogen atoms into helium atoms?
Its called as nuclear fusion. The nucleus of hydrogen atoms fuse together and form helium nucleus. There is some difference of the two masses resulting it to become energy by Einstein's formulae e=mc^2
What fusion in stars occurs to create the element helium?
Hydrogen undergoes nuclear fusion in the core of the sun to form helium.
How is hydrogen changed into helium in nuclear fission?
Hydrogen is not changed into helium in nuclear fission. In nuclear physics, nuclear fusion is a reaction in which two or more lighter atomic nuclei are forced together and are fused into a heavier nucleus. In the case of the formation of hydrogen into helium, our sun does that in what is called the proton-proton reaction.
What is a nuclear equation that shows the overall fusion cycle of the sun?
Nuclear fusion in sun is followed by proton proton chain reaction during this reaction hydrogen fused to form helium the main products of this reaction according to nuclear equation is - positron, neutrino, gamma ray photons, isotopes of hydrogen and helium
What is the process by which stars burn brightly?
Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.
