Question

what was the difference between nuclear fission and fusion full explain and how it work

Answer 1

Hi there!

Nuclear fusion and nuclear fission are two different types of energy-releasing reactions in which energy is released from high-powered atomic bonds between the particles within the nucleus.

The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one.


!! NUCLEAR FISSION !!

Fission is the splitting of a large atom into two or more smaller ones.

♦ Natural Occurrence : Fission reaction does not normally occur in nature.
♦ Byproduct : Fission produces many highly radioactive particles.
♦ Conditions : Critical mass of the substance and high-speed neutrons are required.
♦ Energy requirement : Takes little energy to split two atoms in a fission reaction.
♦ Energy released : The energy released by fission is a million times greater than that released in chemical reactions; but lower than the energy released by
nuclear fusion.

!! NUCLEAR FUSION !!

Fusion is the fusing of two or more lighter atoms into a larger one.

♦ Natural Occurrence : Fusion occurs in stars, such as the sun.
♦ Byproduct : Few radioactive particles are produced by fusion reaction, but if a fission 'trigger' is used, radioactive particles will result from that.
♦ Conditions : High density, high temperature environment is required.
♦ Energy requirement : Extremely high energy is required to bring two or more protons close enough that nuclear forces overcome their electrostatic repulsion.
♦ Energy released : The energy released by fusion is three to four times greater than the energy released by fission.

Hope it helps! :D
