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