Correct answer
Higher melting point than molecular crystals
Explanation
Explanation Covalent network crystals, also known as giant covalent structures , are solids in which each atom is covalently bonded to its neighbors, forming a continuous network of chemical bonds. Examples include diamond, graphite, and silicon carbide . These materials have very high melting points due to the strong covalent bonds that hold them together.
