Nuclear Stability Relative Stability of Different Nuclei.

Nuclear Stability Relative Stability of Different Nuclei Two Methods Which isotopes? Binding Energy What holds an atom together? Forces of Nature and Atomic Structure: Band (Island) of Stability N/Z ratio Number of stable isotopes Isotope trends among the elements: Binding Energy, but first Comparing stability: O-O single bond strength = 146 kJ/mol O=O double bond strength = 496 kJ/mol Which is more stable, O 2 or O 3 ? O 2 : O=O O 3 : O=O-O Predict what you think the trend will be: As atomic number increases, what will happen to stability? Split up class and do: Do all isotopes using Excel Isotopedata_stable.xls Modes of Radioactive Decay U-238 Decay SeriesAnd the problem with radon. Decay modes and the island of stability.
