The geometry around each Si-atom in SiO₂ is
Correct answer: D. Tetrahedral
- A. Trigonal
- B. Cubic
- C. Linear
- D. Tetrahedral
Explanation
The correct geometry around each Si-atom in SiO₂ is tetrahedral. This is because silicon typically forms four covalent bonds, and in SiO₂, each silicon atom is bonded to four oxygen atoms forming a three-dimensional network. The tetrahedral arrangement minimizes electron pair repulsion, which is consistent with VSEPR theory. The other options are incorrect as they do not match the bonding and spatial arrangement around silicon in SiO₂.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
