Match Column I with Column II.
Column I | Column II |
|---|---|
(A) Sorosilicate | (P) Nonplanar |
(B) Amphiboles | (Q) Two-dimensional arrangement of tetrahedra |
(C) Sheet | (R) Shared O per tetrahedron ≥2 |
(D) Cyclic | (S) Charge per tetrahedron <-1 |
| (T) Planar |
Options:
Answer:
Solution:
Sorosilicates share one oxygen atom per tetrahedron, forming nonplanar [Si₂O₇]⁶⁻ units. Each tetrahedron in this structure carries a charge of -3.
Amphiboles are characterized by double chains where at least two oxygen atoms are shared per tetrahedron, resulting in a charge per tetrahedron below -1.
Sheet silicates form a two-dimensional network with three shared oxygen atoms, leading to a charge of -1 per silicon atom. This aligns with the source's tetrahedral-framework convention.
Cyclic silicates feature two shared oxygen atoms and a charge of -2 per silicon atom. Their tetrahedral ring framework is considered nonplanar.
