Covalent Network Solids - MakeTheBrainHappy

Their strength is derived from these intramolecular covalent bonds. They are usually made up of either carbon or silicon, because they can form four covalent bonds with their neighbors and thereby form these structures. There are four common covalent network solids: pure Carbon (C), pure Silicon (Si), Silicon carbide (SiC), and quartz (SiO2).

bond - What type of bonding occurs in isolated silicon

Would isolated silicon engage in network covalent bonding as quartz does or would it engage in a different kind of bonding? Would germanium display similar qualities? I am asking what is the bonding of silicon, not why silicon is different from carbon. I am interested in isolated silicon, not silicon as a …

Is silicon carbide ionic

No. Silicon carbide is covalent. The bond energy of Si -C is generally considered to be lower than that of the C-C, so a simple explanation is that diamond has a stronger bond.
