Short explanation

Recognise that some covalent substances form giant covalent structures such as diamond and silicon dioxide. This objective belongs to Covalent bonding within Chemical bonds, ionic, covalent and metallic for AQA GCSE Chemistry 8462. A strong answer should use giant covalent structure accurately, explain the chemistry behind the statement, and connect the idea back to the exact command in the objective. When revising, separate this point from neighbouring Chemistry ideas by naming the relevant particle, substance, process, calculation, observation, or structure before giving the final conclusion.
