Answer:-
Diamond is a type of solid known as a covalent network solid. In this structure, each carbon atom is strongly bonded to four other carbon atoms in a three-dimensional lattice. These strong covalent bonds extend throughout the entire crystal, making diamond incredibly hard and giving it a very high melting point. This unique structure also contributes to diamond’s exceptional clarity and brilliance. Unlike metals or molecular solids, covalent network solids like diamond don’t have free-moving electrons, which is why diamonds don’t conduct electricity. So, diamond’s strength and durability come from its tightly bonded atomic structure.
