Detailed explanation-1: -Diamond consists of a three – dimensional network of carbon atoms attached to each other. Since carbon atoms have properties for catenation, they form covalent bonds with each other in a 3 – D frame network. Therefore diamond is termed as a network covalent solid.

Detailed explanation-2: -Covalent Network Solids are giant covalent substances like diamond, graphite and silicon dioxide (silicon(IV) oxide).

Detailed explanation-3: -Diamond is a purest form of carbon in which each carbon atom is covalently bonded to four other carbon atoms. Hence diamond is an example of the covalent crystal.

Detailed explanation-4: -In diamond, carbon atoms are held together by a network of covalent bonds. Because the network has many more bonds than a typical molecule, we sometimes refer to network covalent structures as macromolecules.

Detailed explanation-5: -Covalent networks are large, rigid three-dimensional arrangements of atoms held together by strong covalent bonds. Boron, Carbon and Silicon all form covalent networks. They have high melting points because they only contain strong bonds. Examples include carbon in the forms of diamond and graphite.
