Description: The chemical reactions involve the transfer or sharing of electrons, and no change occurs inside the nucleus. Do you know about nuclear reactions? Let's see.

Question

Compare the processes of nuclear fission and fusion as sources of energy.

Accepted Answer

Nuclear Fission Nuclear Fusion

Fission is the splitting of heavier, unstable nucleus into two lighter nuclei by bombarding with the lighter particles. Fusion is the process where, two light nuclei combine, releasing vast amount of energy.

Thermal neutrons are needed to start the fission reaction. Higher amount of energy is needed to start the fusion reaction.

Fission reactions is the main source of power generation, and they are carried out at nuclear power plants. Practically, there are fewer chances to initiate fusion reaction on earth, it mainly occurs on stars or at sun.

Fission is employed in atomic power reactors since it is often controlled. Fusion isn't utilised to supply power, since the reaction isn't easily controlled.

Nuclear wastes are generated during the reaction. Nuclear wastes are not generated during the reaction.
