power
Alpha
Beta
Gamma
Neutron
II. Solve problems involving transmutation and half-life.
Define transmutation:
What new element is formed when an alpha particle strikes aluminum-27 and a neutron is released?
What type of particle is emitted when uranium-235 changes to thallium-231?
The half-life of a radioactive isotope is five days. How much remains of a 200 g sample after twenty days?
III. Explain, compare, and contrast the processes of fission and fusion.
Define fission:
Define fusion:
Create a T-chart that shows at least three similarities and three differences between fission and fusion.
IV. Describe uses for nuclear changes.
Describe two medical uses for nuclear radiation.
V. Diagram the process of energy production in a nuclear power plant.
List the energy transformations that take place as nuclear energy is converted to electrical energy.
Number the following steps in the correct order in the production of electricity from nuclear energy.
Steam produced by boiling water causes the blades of a turbine to rotate.
A neutron bombards a uranium-235 isotope pellet contained in a fuel rod.
Thermal energy released by the reaction is added to water.
Electricity from the generator is carried to the community through wires.
A uranium-235 atom splits, producing two atoms with smaller nuclei, three neutrons, and thermal energy. The speed of the
chain reaction is regulated by control rods, which are made of elements that absorb neutrons. Lowering the control rods
into the reactor will slow the reaction.
The mechanical energy of the rotating turbine blades is transferred to an electric generator.
Superheated water passes through a heat exchanger, where the thermal energy released boils a separate system of water to
produce steam.
VI. Describe risks and dangers associated with nuclear energy.
