Chapter 22, Problem 22.99SP

Interpretation Introduction

(a)

Interpretation:

The shorthand notation of silicate anion in ${\text{K}}_{\text{4}}{\text{SiO}}_{\text{4}}$ needs to be determined.

Concept introduction:

The group 4A elements show variation from non-metals to metals down in the group. The first element of the group 4A is carbon with 4 valence electrons.

Since Si has four valence electrons therefore it shows tetra-valency and can form four covalent bonds with same or different elements. Because of the tetra-valency nature, Si tends to form covalent bonds with same or different elements to form a large number of chemical compounds.

(b)

Interpretation:

The shorthand notation of silicate anion in ${\text{Ag}}_{10}{\text{Si}}_{\text{4}}{\text{O}}_{13}$ needs to be determined.
