1. Properties of carbon
Chapter 4 section 1

2. Key concepts
How is carbon able to form such a huge variety of compounds?
What are four forms of pure carbon?

3. Key terms
Diamond
Graphite
Fullerene
nanotube

4. Carbon atoms and bonding
Few elements have the ability of carbon to bond with both itself and other elements in so many different ways. With four valence electrons, each carbon atom is able to form four bonds.

5. Forms of pure carbon
Diamond, graphite, fullerenes, and nanotubes are for forms of the element carbon.
Diamonds: the hardest mineral which forms deep within the Earth under high temperatures and pressures.
Each carbon atom is bonded strongly to four other carbon atoms.
Extremely hard and non reactive.
Forms crystal structures.

6. Pure forms of carbon
Graphite: A form of the element carbon in which a carbon atom is bonded tightly to three other carbon atoms.
These layers are very weak and can slide past each other.
Pencil marks
Graphite reduces friction between the moving parts

7. Pure forms of carbon
Fullerenes: carbon atoms arranged in the shape of a hollow spere
Nanotubes: carbon atoms arranged in the shape of a long, hollow cylinder, or tube
