1. Relative Stability of Different Nuclei
Nuclear Stability
Relative Stability of Different Nuclei

3. Two Methods
Which isotopes?
Binding Energy

4. What holds an atom together?
Forces of Nature and Atomic Structure:

5. Band (Island) of Stability
N/Z ratio
Number of stable isotopes

8. Isotope trends among the elements:

9. 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, O2 or O3?
O2: O=O
O3: O=O-O

10. Binding Energy: How we measure nuclear stability

13. Predict what you think the trend will be: As atomic number increases, what will happen to stability?

14. Split up class and do:

15. Do all isotopes using Excel
Isotopedata_stable.xls

16. Modes of Radioactive Decay

18. U-238 Decay Series
And … the
problem with radon.

19. Decay modes and
the island of stability.

21. Cool stuff about nuclear chemistry

22. Where is all the Helium From?

23. Uranium-Based Reactors

25. Enrichment:
Diffusion Method; per cycle
Centrifuge Method; 1.3 per cycle

26. 239Pu is fissile and can be used as nuclear fuel.
Breeder Reactors: Good and Bad
238U + n  239U + B-
239U  239Np + B-
239Np  239Pu + B-
239Pu is fissile and can be used as nuclear fuel.

27. Nuclear Proliferation Issues:
The problem with U Enrichment
The problem of Pu materials
