Quartz crystal has typical tetrahedral structure between oxygen and silicon atoms. How many silicon atoms are connected to an oxygen atom in this structure:
Correct answer: A. 4
- A. 4
- B. 3
- C. 2
- D. 1
Explanation
In the typical tetrahedral structure of quartz crystal, each oxygen atom is connected to 4 silicon atoms. This arrangement forms a tetrahedron with one oxygen atom at the center and four silicon atoms at the corners. Each silicon atom shares its four valence electrons with four oxygen atoms, forming strong covalent bonds. As a result, each oxygen atom is surrounded by four silicon atoms in the crystal lattice of quartz.
