(A) SiO
(B) SiO₂
(C) SiO₃
(D) None of these
🧠 Explanation:
- Quartz is primarily composed of silicon dioxide, a naturally occurring compound.
- Its chemical formula reflects a strong bond between one silicon atom and two oxygen atoms.
- This compound forms a crystalline structure commonly found in sand, rock, and mineral deposits.
- Compounds with different oxygen ratios (like SiO or SiO₃) do not match quartz’s typical chemical makeup.
