S2.2.7 Describe the structure of and bonding in silicon and silicon dioxide [SL IB Chemistry]
Both are macromolecules (giant covalent structures) with many strong covalent bonds. Silicon has the same arrangement of atoms as diamond, and silicon dioxide (sand) is the same as silicon - just pop an O atom between each silicon pair. Since there are no delocalised electrons, both chemicals are electrical insulators. (HL only : all atoms are ...

SiO2 Properties
Malco Automotive on Instagram: "But it’s actually science…It works by creating a water-repelling, hydrophobic layer on your exterior paint and a quick-dry agent that makes it even faster and easier to use. Watch the water bead up and run off! With added UV blockers and water-repellant properties combined, SLIK SiO2 is the ultimate in gloss, ease, and protection for your vehicle’s exterior. #detailing #autodetailing #detailersofinstagram #malcoautomotive #carwash"
