graphite

what are the properties of graphite?

- graphite is soft and slippery

- graphite has a very high melting and boiling point

why does graphite have a very high melting/boiling point?

because graphite contains a large number of strong covalent bonds. So, if we want to melt graphite, then we would need to break those covalent bonds. This takes a great deal of energy.

Why is graphite soft and slippery?

Weak forces between the layers allow them to slide over each other easily.

Why does graphite conduct electricity?

Each carbon atom has one delocalised electron that is free to move and carry charge.

graphite is formed from ______________ (multiple words)

layers of carbon atoms arranged in hexagonal rings.

How many covalent bonds does each carbon atom form in graphite?

three covalent bonds

"Describe the structure and bonding in graphite and explain how this relates to its properties."

-Graphite is made of carbon atoms arranged in layers of hexagons.

-Each carbon atom forms three strong covalent bonds with other carbon atoms.

-The fourth electron from each atom is delocalised and free to move throughout the structure.

-The layers are held together by weak forces, allowing them to slide over each other easily.

-This makes graphite soft and slippery.

-The delocalised electrons can move and carry charge, so graphite conducts electricity.
