Chapter 21, Problem 57PS

Interpretation Introduction

Interpretation: To draw the structure and predict the charge for the cyclic silicate ion ${\left[{\text{Si}}_{\text{6}}{\text{O}}_{\text{18}}\right]}^{n-}$

Concept introduction: Silicates are the materials that contain silicon and oxygen in a pattern. Cyclic silicates have a general formula of ${\left({\text{SiO}}_{\text{3}}\right)}_n{}^{2n-}$. The tetrahedral units are linked to form a cyclic structure. Each silicon unit shares two oxygen atoms with the other units.
