WebCovalent network. Graphite is a carbon allotrope. Each carbon atom makes three covalent bonds in this allotrope, leaving one electron in each outer orbital delocalized, resulting in … WebCovalent: The sharing of electron pairs between atoms. The stable balance of attractive and repulsive forces between atoms when they share electrons is covalent bonding. Metallic: The electrostatic attractive force between conduction electrons and positively charged metal ions (sharing of free electrons among a structure of positively charged ions).
