Covalent lattices

  • Covalent bonds are bonds between nonmetals in which electrons are shared between the atoms

  • Covalent compounds can be arranged in simple molecular or giant molecular lattices

    • Simple molecular lattices: iodine, buckminsterfullerene (C60) and ice

    • Giant molecular: silicon(IV) oxide, graphite and diamond
