Identify the characteristics that differentiate between the radiation particles of table O
Define an unstable nucleus.
Explain and use Table N to write a balanced nuclear decay equation
Defend the statement: “nuclear equations obey the law of conservation of mass, matter &
charge.”
What is the distinction between the penetrating power of alpha and gamma particles?
What happens if alpha and beta particles are moved through a magnetic field?
Explain and use table N to compute for any radioisotope:
a. The half-life of a sample
b. The number of half-lives that have past for a decay of a radioisotope
c. The mass or fraction remaining for a radioactive sample.
The ratio of carbon-14 to carbon-12 in a chunk of charcoal from an archeological dig is
determined to be one half the ratio in a freshly cut piece of wood. How old is this dig site?
Contrast artificial and natural transmutation.
Compare and contrast fission and fusion reactions.
Discuss at least three benefits of nuclear power plants.
Discuss costs of nuclear power plants.
Which form of reaction releases the most energy?
Explain how the mass defect for radioactive nuclei confirms E= mc2.
Explain why it is important that radioactive isotopes used internally for diagnosis or treatment
have relatively short half-lives?
List the isotopes used in dating.
List the isotopes used in medicine.
