Step-by-step explanation:
Nuclear fission :-
1. In a nuclear fission , a heavier nucleus splits into a smaller nuclei.
2. In a nuclear fission , harmful nuclear radiations are emitted.
3. A nuclear fission starts when
a slow neutron bombards the heavy nucleus. Like , Uranium - 235
4. Nuclear fission is a chain reaction ie :- It multiples very fast.
5. Nuclear fission reactions can be controlled to produce electricity.
6. Nuclear fission reactions can be used to produce a large amount of energy.
7. Temperature plays no role in starting nuclear fission reaction.
8. By - products of nuclear fission reactions are radioactive and produces harmful radiations.
9. Nuclear fission causes more pollution.
10. In a nuclear fission , the disposal of nuclear waste is a big problem.
Nuclear fusion :-
1. In a nuclear fusion , light nuclei combine to form a heavy nucleus.
2. In a nuclear fusion , no harmful radiations are emitted.
3. A nuclear fusion starts when like nuclei are heated at extremely high temperature.
4. Nuclear fusion is not a chain reaction.
5. Nuclear fusion reactions are still uncontrolled and can't be used to produce electricity.
6. Nuclear fusion reactions produce much more energy than that of the nuclear fission.
7. Temperature at order of 10⁷ K us required to start the nuclear fusion reaction.
8. By - Products of nuclear fusion are not radioactive and hence donot produces harmful radiations.
9. Nuclear fusion causes no pollution.
10. In a nuclear fusion, no such problem is there.

Step-by-step explanation:
Both fission and fusion are nuclear processes by which atoms are altered to create energy, but what is the difference between the two? Simply put, fission is the division of one atom into two, and fusion is the combination of two lighter atoms into a larger one. ... Nuclear fission releases heat energy by splitting atoms.
