WebSilicon – a shiny grey solid, an electrical conductor and has a high melting point (metallic properties) but is very brittle and has a low density (non-metallic properties). previous 1 WebAug 15, 2024 · Silicon has high melting and boiling points due to its network covalent structure. Melting or boiling silicon requires the breaking of strong covalent bonds. Because of the two different types of bonding in silicon and aluminum, it makes little sense to directly compare the two melting and boiling points. The four molecular elements
