Chapter 23 Outline

1. Natural Radioactivity. This section outlines the three different forms of radiation, alpha particles, beta particlas and gamma radiation. The mass, charge, and characteristics are discussed. This goes back to the experiment by Rutherford discussed last semester.
2. Nuclear Reactions and Radioactive Decay. This section discusses different radioactive processis and balancing nuclear reactions. Note that the mass is preserved. You should be able to determine the products from alpha emission, beta emission, positron emission, and electron capture.
3. Stability of Atomic Nuclei. This section is to help you determine what isotopes of a particular element will be radioactive.
4. Rates of Nuclear Decay. First order kinetics for radioactive decay. Discuss half life, you should be able to relate this to the integrated rate equation for a first order reaction. This is used for radio dating.
5. Artificial Nuclear Reactions. Nuclear reactions to produce artificial elements and isotopes. This is done with particle accelerators and nuclear reactors.
6. Nuclear Fission. This is a reaction that results in an atom breaking into fragments. Used for energy production.
7. Nuclear Fusion. This is the reaction when atoms are combined. The reaction used by the sun to produce energy.
8. Radiation Health and Safety. Discusses radiation dose and effect.
9. Applications of Nuclear Chemistry. Applicaitons include medical, analysis, and food stability.
