✔ 最佳答案
Graphite shouldn't be covalent compound, 佢只係d carbon atom係linked by covalent bond.正確來講佢係covalent substance,有一個giant covalent structure.
*Covalent substance is not equal to covalent compound

同埋graphite內面只有carbon atoms,無其他,所以唔係compound

The reason is that graphite is NOT a compound.
Graphite is an allotrope (a form) of carbon, which is an element.
