1 Nuclear Chemistry

2 Nuclear Chemistry Objectives Students will be able to identify what radioisotopes are and why they undergo radioactive decay. Students will demonstrate understanding of radioactive decay through applications and graphing. Students will understand and classify nuclear reactions by the types of radiation produced.

3 ICP : 10/28 Objectives: Atomic Structure Unit Exam I can use the band of stability graph to predict if an isotope is radioactive. Homework: Band of Stability Wksht.: Read and plot isotopes on band of stability graph.

4 ICP : 10/29 Due: Band of Stability Worksheet Objectives: I can use the band of stability graph to predict if an isotope is radioactive. Homework: Band of Stability Wksht.: Graph isotopes and predict if radioactive.

5 Nuclear Band of Stability http://www.hasdeu.bz.edu.ro/softuri/fizica/mariana/Atomica/Table/lessons/11nuclear/nuclear.h tm

6 Band of Stability Graph Analysis 1. What subatomic particles determined if each isotope had a stable nucleus? 2.Explain how the band of stability graph helps you determine if an isotope has a stable nucleus or not? 3. Does Xe-131 or Xe-135 have an unstable nucleus? Explain how you know this.

8 Radioisotopes Atoms with unstable nuclei. The ratio of protons-to-neutrons is not adequate for nuclear stability. Most elements need more neutrons than protons to maintain stability within the nucleus.

9 A reaction that occurs within the nucleus of a radioisotope in order to stabilize it. Also called: radioactive decay; radioactivity Spontaneous Reactions (occurs naturally). Reaction rates (speed of reactions) remain constant. Nuclear Reactions

10 ICP : 10/30 Objectives: I can use the band of stability graph to predict if an isotope is radioactive. I can model, graph, and interpret radioactivity. Homework: Radiometric Dating Graph Worksheet

12 Chemistry I : 10/31 Objectives: I can use the band of stability graph to predict if an isotope is radioactive. I can model, graph, and interpret radioactivity. Complete M&Mium Lab Homework: Complete post-lab qts. for M&Mium lab. Study for Radioactive quiz (tomorrow).

13 Radioactive Decay Lab Purpose: Simulate and graph the radioactive decay of an artificial radioisotope, M&Mium. Pre-Lab Questions: 1.What side of the candy represents the parent isotope? 2.What side of the candy represent the daughter isotope? 3.What is the half-life of the M&Mium radioisotope?
