  • Difference Between Silicon and Silica | Compare the

    Summary – Silicon vs Silica. The key difference between silicon and silica is that silicon is a chemical element whereas silica is a chemical compound. Both silica and silicon have lattice structures. But silica differs from silicon due to the presence of silicon-oxygen covalent bonding. This accounts for the basic difference between silica
