Additional Fission And Fusion
Fusion and fission are totally different in how they take place but all end up in production of energy. While one involves the splitting of large unstable nucleus the other involves combination of nuclei. How conversant are you with these two reactions? Take up this quiz and review what you know so far!

- D.
Positive charged particle found in the shells, mass 1/2000
- E.
Negative charged particle found in the shells, mass 1/2000
