Best Answer

The nuclear reaction within the Sun is fusion. Four hydrogen nuclei (four protons) are forced together under the intense pressure present to form a helium nucleus (two protons and two neutrons). The neutrons are formed from protons by the weak interaction. The resulting loss of mass is accompanied with a release in binding energy, which drives the cycle and emits tremendous radiation energy.

How does nuclear fission happen in the central of the sun?

The Sun gets its energy from fusion, not from fission. Ocassionaly an atom of a heavier element might go through fission, but that's hardly relevant for the working of the Sun.The Sun gets its energy from fusion, not from fission.

What does happen within the sun is it fission or fusion?

Fusion only, there are no heavy elements like uranium so there can be no fission taking place


What are benefits fission and fusion gives us?

Fission gives us electricity from nuclear power plants. Fusion gives us the sun


Did the energy that is stored in fossil fuels come from fission or fusion reactions from the sun?

Not fission. The sun's energy is produced by nuclear fusion, and that energy produced all the vegetation which turned into fossil fuel.


What is the difference a fission and fusion?

fission is the splitting of atoms of uranium or plutionium by the means of neutrons. fusion is the opposite. fusion is the violent combining of atoms through magnatism and heat. our own sun uses fusion to shine.
