CHM 11500 Lectures 4, 5, 6 Reading Assignment: Sections 23.1-23.9, pp. 1060-1090. Learning Objectives: Understand these Concepts How nuclear changes differ in general, from chemical changes. The meanings of radioactivity, nucleon, nuclide, and isotope. Characteristics of three types of radio active emissions, a, B, and g The various forms of radioactive decay and how each changes the values of A and Z. How a decay series combines numerous decay steps and ends with a stable nuclide. Why radioactive decay is a first-order process; the meanings of decay rate and specific activity. The meaning of half-life in the context of radioactive decay. How radioisotopes are used in research, analysis and diagnosis. Why the mass of a nuclide is less than the sum of its nucleon’s masses (mass defect) and how this mass difference is related to the nuclear binding energy. How nuclear stability is related to binding energy per nucleon. How unstable nuclides undergo either fission or fusion to increase their binding
