'''Nuclear Fission ''' | '''Nuclear Fusion'''
In this process , a heavy nucleus is when striked by neutrons, it breaks into two or more light nuclei and liberates a huge amount of energy | In this process , two or more light nuclei fuse together to form a heavy nucleus and liberates a huge amount of energy.
Energy released is about 200MeV. | Energy released is about 26.7MeV .
Neutrons are emitted in this process. | Protons are emitted in this process.
A chain reaction is initiated in this process. | It does not give rise to chain reaction.
It takes place spontaneously at ordinary temperatures. | It takes place at very high temperatures about 10° C.
It can be performed at controlled conditions . | It cannot be performed under controlled conditions.
Radioactive substances are emitted in this process like alpha , beta , gamma .| It doesn't emit any kind of radioactive radiation.
