1. Survey of the Elements: 1. Element structures 2. Oxide structures 3. Cool things about some elements

2. Structures of the Elements

3. Metals: Close packing

5. Number of Bonds Possible:

9. α-R boron β-R boron γ-boron Allotropes of Boron: linked B 12 icosahedra

10. Traditional Allotropes of Carbon

12. New Allotropes of Carbon: Fullerenes C 60

13. New Allotropes of Carbon: Nanotubes

14. New Allotropes of Carbon: Graphene

15. Industrial Production of Diamonds

17. Why is diamond formed, and not graphite? Reason 1. Reverse Reaction favors Graphite Instability H + diamond  CH4, but slower than CVD diamond growth H + graphite  CH4, but faster than CVD graphite growth Reason 2. Forward Reaction favors Diamond Formation sp 3 C atoms on surface (show structures) slow sp 2 graphite formation. H 2 (g)  2 H(g) H(g) + CH 4 (g)  CH 3 (g) + H 2 (g) CH 3 + C(diamond-H, surface)  Diamond-CH 3 + H
