Chem 165 Class 15 Chapter 23: Nuclear Chemistry Suggested End-of-chapter problems for Chapter 23 (those covering today’s material in bold ) Chapter 23: 5 , 6 , 14 , 15 , 16 , 17, 18, 20, 23 , 24, 25, 26, 33 , 34 , 36 , 55 , 57 , 62 , 68, 79, 85 Caption : Nuclear fission reactions, such as this one associated with the uranium-235 chain reaction, involve radioactive decay that are both initiated by absorption of neutrons and result in emission of nuclear particles (as well as γ rays). In the case of uranium-235 fission, this can result in a chain reaction that ultimately generates a tremendous amount of energy. from URL: http://www.visionlearning.com/library/module_viewer.php?mid=59 ARIS: Chapter 13-C: assignment due Friday (3/6) at 6:00 pm CST bjective today: 1. Discuss nuclear equations associated with various types of radioactive decay 2. Explore patterns of nuclear stability Text: Chapter 23: Section 1 – 4; Next class: Chapter 23: Section 2 – 6 ARIS: Chapter 23-A: assignment due Monday (3/9) at 6:00 pm CST

Chem 165 Class 15 Recall: the nucleus can contain two types of nucleons : protons (positively charged) neutrons (neutral) Atomic number: # of protons Mass number: # protons + # neutrons Chapter 21: Nuclear Chemistry A. Radiation and Nuclear Reactions Review: The Nucleus: Review: Isotopes Not all atoms of the same element have the same mass due to different numbers of neutrons in those atoms. Example: There are three naturally occurring isotopes of uranium: – Uranium-234: – Uranium-235: – Uranium-238: Nuclide : nucleus associated with a given isotope U 234 92 U 235 92 U 238 92 (redundant)
