Question

what is the difference between nuclear fission and nuclear fusion?

Answer 1

Both fission and fusion are nuclearreactions that produce energy, but the applications are not the same. Fissionis the splitting of a heavy, unstable nucleus into two lighter nuclei, andfusion is the process where two light nuclei combine together releasing vast amounts of energy.

nuclear fusion
-------------------------------------------------------
1) small nuclei will combine with each other to from an large nuclei

2)it is not a chain reaction  

3)the process of fusion reaction cannot be controlled 

4)very high amount of energy  is required for this process to take place

5)high amount of energy is released
------------------------------------------------------------------------------------------------------
nuclear fission
----------------------------------
1) larger nuclei will split to from an smaller nuclei

2)it is a chain reaction 

3)the process of fission reaction can be controlled 

4)less amount of energy is enough for this process

5)energy released is very high but less than that of fusion
