Question

the reactions that take place in the center of the sun are

Answer 1

nuclear fission takes place at centre of the sun

Answer 2

Helloo!

Nice question!!


In sun Nuclear fusion takes Place...
Nuclear energy released by fusion of two light elements.
The power that fuels the sun and the stars is nuclear fusion. two isotopes of hydrogen, deuterium and tritium are fused to form a nucleus of helium and a neutron. This fusion releases 17.6 MeV of energy. Unlike nuclear fission, there is no limit on the amount of the fusion that can occur inside the core of Sun or any Star...

These reaction occurs!!

D + T -> 4He + n + 17.6 MeV Merging a nucleus of deuterium with tritium nucleus of a helium nucleus consisting of two neutrons and two protons, releasing a 1 neutron and 17.6 MeV of energy.

D + D -> 3He + n + 3.2 MeV Merging Two Deuterium nuclei a Helium nucleus consisting of two protonsand one neutron, releasing a 3.2 MeV neutron and obtaining energy.

D + D -> T + p + 4.03 MeV 
Merging Two Deuterium nuclei, a nucleus of tritium, we obtain a proton and 4.03 MeV.

hope it helps!!
