Graphite

Question 1

What is Graphite formed from?

Answer 1

• Carbon atoms.
• Each carbon atom forms 3 covalent bonds.
• ## Carbon atoms form hexaganol rings.

Question 2

Why does graphite have a high melting and boiling point?

Answer 2

• Many strong Covalent bonds.

- Takes a great deal of energy to break them down.

Question 3

What is the first property?

Answer 3

• The hexagonal rings are in layers.
• No covalent bonds between these layers.
• So they can slip and are slippery.

Question 4

What is the second property?

Answer 4

• good conductor of electricity and heat.
• Each Carbon atom has a single electron not in a covalent bond in its outer shell.
• These electrons are released from the carbon atoms.
• Delocalised electrons.

Question 5

What are delocalised electrons?

Answer 5

• ## delocalised electrons can move. this means that they can conduct heat and electricity.

Question 6

How is graphite similar to an metal?

Answer 6

• Both are good conductors of heat and electricity.

- Both have delocalised electrons that can move.
