Graphite Structure and Properties

The video explores whether the bonds in graphite are ionic or covalent. It explains that graphite is composed solely of carbon atoms, which are non-metals, leading to covalent bonding. The structure of graphite is described as a giant covalent structure, with carbon atoms forming sheets that can slide over each other, making graphite a good lubricant. Graphite also conducts electricity and is relatively soft. The video concludes by summarizing that graphite's bonds are covalent, forming a large structure.
