Covalent Bonding: This is the type of bonding that holds the carbon atoms together within each layer of graphite. It involves sharing electron pairs between atoms.
Delocalized Electrons: In graphite, one electron from each carbon atom becomes delocalized. These electrons are free to move across layers, allowing graphite to conduct electricity.
Allotropes: Different physical forms in which an element can exist. Graphite is one allotrope of carbon; diamond is another.
