Question

Read the following statements and answer as true or false.

Diamond is a good conductor of electricity.
If true enter 1, else enter 0

Answer 1

Diamond is a good conductor of heat because all the electrons are close together due to a strong bond between the atoms causing vibrations
Diamond is not a good conductor of electricity because there are no free electrons flowing around in the structure of the diamond.

Diamond has a unique atomic structure. Each of the Carbon atom's valence electrons is taken up in covalent bonding, so each electron is localised. This means that no one electron is free to pass an electric current through the Diamond - thus, Diamond cannot carry an electrical current; there is nothing to pass the current through.
