What kind of bonding and structure tends to be associated with low melting points and boiling points?
Simple molecular covalent
giant ionic lattice
giant molecular covalent
metallic
Which kind of bonding and structure allows substances to conduct electricity when solid?
Metallic

Ionic
What happens in terms of subatomic particles when ionic bonds are formed?
loss and gain of electrons
shared pair of electrons
a sea of delocalised electrons
Why does sodium chloride conduct electricity when molten but not when solid?
molten ions can move freely
they're too cold when they're solid
they have too much energy
Name a substance that has a very high melting point and is a non-conductor of electricity in any state.
Diamond
Graphite
Graphene
Buckminsterfullerene
Why do lattice structures usually have high melting points?
Lots of energy is needed to break so many (strong) bonds.
Lots of energy is needed to break so many (weak) bonds
Why does sodium metal conduct electricity?
It contains a sea of delocalised electrons that can carry a current
It can easily move ions around a circuit
metals conduct electricity
