In graphite, each carbon is bonded to three others in a planar structure, indicating sp\textsuperscript{2} hybridization.
In diamond, each carbon is tetrahedrally bonded to four other carbons, representing sp\textsuperscript{3} hybridization.
In C60} (buckminsterfullerene), carbon atoms also form a structure using sp\textsuperscript{2} hybrid orbitals.
