Acrystal of graphite contains which type of bond?

Graphite has a giant covalent structure in which: each carbon atom is joined to three other carbon atoms by covalent bonds.

Graphite has a giant covalent structure in which:

each carbon atom is joined to three other carbon atoms by covalent bonds

the carbon atoms form layers with a hexagonal arrangement of atoms

the layers have weak forces between them

each carbon atom has one non-bonded outer electron, which becomes delocalised:

they are all solids.
