1. What is one benefit associated with a nuclear fission reaction?
1) The products are not radioactive.
2) Stable isotopes are used as reactants.
3) There is no chance of biological exposure.
4) A large amount of energy is produced.
2. Compared to an ordinary chemical reaction, a fission reaction will
1) release smaller amounts of energy
2) release larger amounts of energy
3) absorb smaller amounts of energy
4) absorb larger amounts of energy
3. What is the primary result of a fission reaction?
1) conversion of mass to energy
2) conversion of energy to mass
3) binding together of two heavy nuclei
4) binding together of two light nuclei
4. The diagram below represents a nuclear reaction in which a neutron bombards a heavy nucleus.
Which type of reaction does the diagram illustrate?
1) fission
2) fusion
