Question 16

What are the similarities between diamond and graphite?

Answer 16

High melting and boiling points
Giant covalent lattice
Don’t dissolve in water

Question 17

Name differences between diamond and graphite

Answer 17

Graphite is soft, diamonds hard
Layers of atoms in graphite can slide over each other
Only graphite conducts electricity and heat (delocalised electrons)

Question 18

Why can metals conduct electricity?

Answer 18

The sea of delocalised electrons between the metal ions are free to move anywhere in the structure and carry a charges
