4.2.2.6 Giant covalent structures

Content

  • Substances that consist of giant covalent structures are solids with very high melting points. All of the atoms in these structures are linked to other atoms by strong covalent bonds. These bonds must be overcome to melt or boil these substances. Diamond and graphite (forms of carbon) and silicon dioxide (silica) are examples of giant covalent structures.

Students should be able to recognise giant covalent structures from diagrams showing their bonding and structure.
