Which of the following non-metals is the best conductor of electricity?

The Correct answer is Graphite.

Key Points

• Graphite is an allotrope of carbon.
• It is the only non-metal that is a good conductor of electricity.
• This conductivity is due to the presence of free electrons in its structure.
• Graphite has a layered structure with weak forces between layers, allowing electrons to move freely.
• It is used in applications such as electrodes and batteries due to its conductive properties.

 Additional Information

• Phosphorous
  • Phosphorous is a non-metal, but it is not a conductor of electricity.
  • It is highly reactive and is used in fertilizers, detergents, and fireworks.
• Bromine
  • Bromine is a non-metal and is a liquid at room temperature.
  • It does not conduct electricity and is used in flame retardants and certain types of medication.
