No. Stars are only in the main sequence when they are fusing hydrogen.
If you are asking where does solar nuclear fusion take place, then that would be at the core of stars.
Nuclear fusion; hydrogen into helium.
A protostar does not burn fuel as it is still taking part in nuclear fusion. It is, however, preparing to become a main sequence star, and will then burn mostly hydrogen at that stage.
Nuclear fusion of hydrogen isotopes take place to form helium.
The sun's nuclear reactions are fusion reactions at extremely high temperatures and pressures, while the nuclear reactor's nuclear reactions are fission reactions at typical temperatures and pressures for earth.
It is called fusion. It is the process taking place on our sun, as two hydrogen atoms fuse together to form a helium atom and give off a small amount of energy while losing some mass.
Fission is the process of taking a heavy element and splitting it into two or more smaller elements. Whereas fusion is the process of forming a heavier element by fusing two or more smaller elements.
Helium
Sodium originated in the nuclear reactions taking place inside stars.
Yes, and it is formed from the process called nuclear fusion. The sun's own energy comes from nuclear reactions taking place in the sun's core.
Nuclear fusion is taking place in the Sun's core that makes the solar energy. Hope this helped! :)
-- In the cores of stars, where nuclear fusion reactions are taking place. -- Inside the casing of a nuclear weapon at the moment of detonation. -- In the fuel rods in the core of a nuclear power generating station. -- At the point of collision in the experimental target area in a particle accelerator.
