Question
The fundamental structural building block of all silicate minerals is the $SiO_4^{4-}$ ion. What is the geometry and hybridization of the silicon atom in this unit?
Answer: C
💡 Solution & Explanation
The basic repeating unit of all silicates is the $SiO_4^{4-}$ anion. The central Silicon atom undergoes complete $sp^3$ hybridization and is bonded to four Oxygen atoms at the corners of a regular tetrahedron.
