9. First Topic Where do all these elements come from? How are they made? Are they made?

11. What aspects of this should we explain?

12. What will our explanations depend on? Thermodynamics: relative stability Kinetics: rate and mechanism

13. General Decrease in Abundance with Atomic Number

14. Even > Odd

15. Peak at Fe

16. Peak at Pb

17. Trough at Be

18. Missing Tc and Pm and Above N = 83

19. Nuclear equations

21. Nucleosynthesis of the Elements Hydrogen Burning 1 H + 1 H  2 H + e + + v e­ 2 H + 1 H  3 He +  3 He + 3 He  4 He +2 1 H Why does this happen only in stars? 4 1 H  4 He + 2e + + 2v e

22. Helium Burning 4 He + 4 He  8 Be 8 Be + 4 He  12 C*  12 C +  3 4 He  12 C +  Is this easier or harder than hydrogen burning?

23. Carbon Burning, etc. 12 C + 4 He  16 O +  16 O + 4 He  20 Ne +  20 Ne + 4 He  24 Mg +  12 C + 12 C  24 Mg +  12 C + 12 C  23 Na + 1 H 12 C + 12 C  20 Ne + 4 He Go back to initial Questions. Can we answer any?

24. The  -Process 20 Ne +   16 O + 4 He 20 Ne + 4 He  24 Mg +  2 20 Ne  16 O + 24 Mg +  40 Ca + 4 He  44 Ti* +  44 Ti* + e -  44 Sc* + v + 44 Sc*  44 Ca +  + + v + 44 Ca + 4 He  48 Ti + 

26. Neutron Capture-Beta Decay
