Describe the structure of graphite and how it relates to its ability to conduct electricity.

Graphite has a layered structure made up of hexagonal rings of carbon atoms. Within each layer, the carbon atoms are bonded covalently, but there are no covalent bonds between the layers, allowing the layers to slide over each other. The delocalised electrons between the layers enable graphite to conduct electricity.

This answer is strong as it connects the structural features of graphite with its electrical conductivity. It tests the student's ability to describe the structure and relate it to a specific property, demonstrating both recall and understanding.
