Properties and Structure of Graphite

The video explores whether graphite is a metal or non-metal, explaining that it is composed solely of carbon atoms, classifying it as a non-metal. Graphite is better described as a covalent or molecular compound. The structure of graphite is a giant covalent structure with sheets that slide over each other, making it a good lubricant. Despite being made of non-metals, graphite conducts electricity due to delocalized electrons.
