Question

Quizplus · Accepted Answer

Covalent network solids are extremely hard and have extremely high melting and boiling points because of the strong covalent bonds holding the atoms together. Diamond (C) is an example of a covalent network solid. The other compounds listed do not form covalent network solids because they do not have a three-dimensional network of covalently bonded atoms. Li is a metal and forms a metallic solid, O₂ and CO₂ form molecular solids held together by intermolecular forces.
