is diamond a compound?

yes form of carbon

No, diamond is not a compound. Diamond is a pure element made up of carbon atoms arranged in a crystal lattice structure. Specifically, each carbon atom forms four strong covalent bonds with its neighboring carbon atoms, creating a three-dimensional network of interconnected carbon atoms. This unique arrangement gives diamond its exceptional hardness and brilliance. Unlike compounds, which consist of two or more different elements bonded together, diamond is composed only of carbon.
