Question

Name the type of the structure of silicate in which one oxygen atom of [SiO4]4−[\text{SiO}_4]^{4-} is shared?

A

Sheet silicate

B

Pyrosilicate

C

Three dimensional silicate

D

Linear chain silicate

Step-by-Step Solution

In silicates, the basic structural unit is the [SiO4]4−[\text{SiO}_4]^{4-} tetrahedron. Depending on the number of oxygen atoms shared between adjacent tetrahedra, silicates are classified as follows:

  • Orthosilicates: No oxygen atom is shared.
  • Pyrosilicates: One oxygen atom is shared between two tetrahedra.
  • Chain or Cyclic silicates: Two oxygen atoms are shared.
  • Sheet (Phyllosilicates): Three oxygen atoms are shared.
  • Three-dimensional (Framework) silicates: All four oxygen atoms are shared. Therefore, the silicate structure in which one oxygen atom is shared is a pyrosilicate.
