Chemistry Final Review By: AP Chemistry Class Nuclear...Some Definitions ? Nucleons-any particle found in the nucleus - ex(protons and neutrons) ? Nuclide-atom defined by # of protons and neutrons in nucleus ? Isotopes-same # of protons, but different # of neutrons ? Attraction stronger in nucleus than repulsion ? Hideki Yukawa Nuclear Types of forces: ? Strong Nuclear Force-interaction that binds nucleons together when very close...short distances=larger nuclei Nuclear Binding energy: ? When protons and neutrons come together, energy released ? More stable=Lower Energy ? Nuclear Binding energy-energy released when nucleons come together ? Mass of atom < combined masses of separate parts

1 AP Chemistry Chapter 21 - The Nucleus: A Chemist?s View 21.1 Nuclear Stability and Radioactive Decay A. Radioactive Decay 1. Decomposition forming a different nucleus and producing one or more particles a. Total mass number and atomic number must be conserved in any nuclear change nCHeBe 101264294 +?+ B. Zone of Stability 1. Of 2000 known nuclides, only 279 are stable with respect to radioactive decay 2. All nuclides with more than 83 protons (bismuth) are unstable 3. Light nuclides are most stable when the neutron/proton ratio is 1 4. Heavier nuclides are most stable when the neutron/proton ratio is greater than 1 5. Magic numbers a. Special stability exists when the number of protons or neutrons is: 2, 8, 20, 28, 50, 82, 126 C. Types of Radioactive Decay
