There are two similar words to describe nuclear reactions. Fusion, in which smaller atoms are fused together to produce energy, and fission, in which giant atoms are caused to break apart, also releasing energy. Similar, but opposite.
The Sun, and all the stars, form using fusion, in which atoms of hydrogen merge to form atoms of helium. For old stars that have used up much of their hydrogen, helium atoms can fuse again to become carbon or oxygen.
Fission power is similar to the nuclear powerplants here on Earth, in which uranium atoms break apart into lighter elements.
What else can I help you with?
The source of the sun's energy is?
Nuclear fussion
Which kind of nuclear reactions is the source of the sun's energy?
Nuclear fussion of Hydrogen to give helium, positron and energy
Where does nuclear fussion only take place in the sun?
Only at the core where the temperature and pressure is high enough.
What two names are given the sun's energy?
Solar energy and sunlight are the two names given to the sun's energy.
What is the release of matter and energy from nuclear decay?
Fussion
Where in space do fission and fussion reactions happen and what is the result?
Fission and fussion manly occar in a star or a sun. The reason that a star or a sun is bright is because of the heat that is given off of from fission and fussion.
How are nuclear fission and fussion the same?
Both release excess nuclear binding energy.
What process does nuclear energy go through?
If you're referring to nuclear energy in power generating plants, it is nuclear fission. If you're referring to the nuclear energy in our Sun, it is nuclear fusion.
What is nuclear fusion on the sun and where does it occur?
nuclear fusion is when 2 hydryon atoms combine or FUSE together. when this happens the neculous combine therefore causing nuclear fussion which releaces masses of heat and light enegry that radiates to earth
Where can nuclear fussion be found?
The cores of stars and hydrogen bombs.
Are the products of nuclear fussion radioactive?
no, but the products of fission are radioactive
Is uranium on the sun?
Yes, uranium is present on the sun, but in very small amounts compared to other elements. Uranium is created through nuclear fusion reactions in stars like the sun, but it is not a major component of the sun's composition.
