Question

Quizplus · Accepted Answer

A substance with a very high melting point, hardness, and non-conductor properties when both solid and molten is characteristic of a network solid, which is a type of solid where the atoms are connected in a continuous network through covalent bonds. Examples of network solids include diamond, quartz, and graphite. Metallic solids conduct electricity, ionic solids are typically brittle and conduct electricity when molten or dissolved, nonpolar molecular solids have low melting points and are typically soft, and polar molecular solids have weaker intermolecular forces and low melting points.
