Nuclear fusion is a process in which production of energy is taking place by colliding of lighter atoms( mostly hydrogen)

Explanation:

Isotopes of hydrogen are mostly used in these types of reactions.

Deuterium and Tritium are those two isotopes which perform the Nuclear Fusion reaction.

When they fuse together ( high energy is required to fuse them i.e. High pressure minimum of 10^6 pascal and temperature of about 10,000 degree C )

They release huge amount of energy which is equivalent to the energy produced by 1000 KJ of coal burning together.

They recombine to form an helium atom and a fast moving neutron.
There is also reaming of an extra mass which is represented by Einstein's equation,
E=mc^2

Here is the diagram to show this process,

The most common nuclear fusion reaction takes place in the stars.
Here is how it takes place:-

The center of the stars has **huge amount of chemical activities ** taking place inside them.

Collision of atoms take place(i.e. atoms of Hydrogen) releasing tremendous amount of energy.

This reaction involves the fusion of many nuclei which on fusing make a larger nuclei. This particularly releases energy which is responsible for fueling the stars.
