1. Science 10

2.  Non-metal atoms sharing electrons  Can form two structures:  Simple molecular structure (last class) ◦ Simple, small molecules ◦ Strong intra-molecular covalent bonds ◦ Weak intermolecular bonds (between molecules) ◦ Low melting and boiling points  Giant covalent structure ◦ Huge, 3-D structure ◦ Strong intermolecular bonds lead to high melting and boiling points

3.  Element, solid, non-metal  Atomic Number =6, Atomic mass=12.01 amu  Has many allotropes – different molecular forms (configurations/structures) in the same state  Can you think of some?

4.  Diamond  Graphite  Fullerenes (buckyball)  Carbon nanotubes

5.  Make a table with four headings: ◦ Diamond ◦ Graphite ◦ Buckminsterfullerne (C 60 ) ◦ Carbon nanotubes (CNT) List all the properties you can think of. Then discuss and compare tables as a class.

7.  LifeGem – Company based in Illinois, USA  www.lifegem.com www.lifegem.com  Scroll down and select the “created from carbon” hyperlink to see the process  Cool, eh?

8.  O – Oxygen (O 2 ) and Ozone (O 3 )

9.  Will have different structure  Will have different chemical and physical properties (eg. Reactivity or colour)  Different potential uses in the scientific community and society
