Define the term allotropes
Atoms with same proton number but different number of neutrons
Atoms with same proton number but different mass number
Atoms in different arrangement but same structure
Atoms in different arrangement and different structural form
Graphite, diamond and Buckminsterfullerene are all allotropes of
Berylium
Silicon
Germanium
Carbon

graphite
diamond
fullerene
graphene
Which has a 3D tetrahedral structure?
graphite
diamond
fullerene
none of these
Graphite is soft because
it has strong covalent bonds
its layers can slide over one another due to weak forces between the layers
it has weak van der Waals forces between layers
it is used as a lubricant
Which of the following Allotropes of Carbon are good lubricators?
Graphite
Graphene
Diamond
Why can diamond not conduct electricity and heat?
because each carbon is bonded to 3 others
because it has a sea of delocalised electrons around it
because all electrons are bonded in strong covalent bonds
because atoms form weakly attracted layers
