Where the nucleus is not in a stable configuration, it may change spontaneously to try to achieve a more stable state. This results in radioactivity of alpha, beta, and gamma types usually, though there are other variations. Also some heavy nuclei such as Uranium 235 and Plutonium 239 are easily fissioned or split when a neutron is captured, because the binding energy of the resulting lighter nuclei is greater than that of the heavy one.

Why does the sun emit heat and light?
The heat and light emitted from the sun comes from the nuclear reactions that occur on it.
Is it true that the sun glows due to nuclear reactions in its corona?
No, the nuclear reactions are at the sun's core. It glows because the outer layers are at about 6000 degC and therefore it is incandescent
What types of reactions occur in a star?
The nuclear reaction that happens in a star is called fusion. A star's energy comes from this atomic reaction. This is what makes stars extremely hot and bright.
What gas is exchanged into helium in a stars nuclear reactions?
Hydrogen
What is the name of the remains of the sun after its nuclear reactions stops?
neutron star
Spontaneous nuclear fission processes occur by?
chain reactions
What does the inner core do for the sun?
That's where the nuclear reactions occur that keep it lit.
What is naturalization reaction?
Natural nuclear fusion reactions occur in all stars
The rate at which reactions occur in a nuclear reactor is regulated by?
number of control rods
Where in the sun do most of the nuclear reactions occur?
At the center, where the gravitational pressure is highest.
What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
Can the production of new atoms occur doing a chemical reaction?
No, it is not possible; we need nuclear reactions for this.
What is the difference between the nuclear reactions in a nuclear reactor and those in an atomic bomb?
Nuclear reactions in a nuclear reactor are controlled reactions. The reactions in the atomic bomb are not controlled reactions
Fusion reactions on the sun?
yes nuclear fusion does occur on the sun, creating intense heat and light
Why does the sun emit heat and light?
The heat and light emitted from the sun comes from the nuclear reactions that occur on it.
What is the difference between the nuclear reactions taking place in the sun and the nuclear reactions taking place in a nuclear reactor?
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.
