The basic structural unit of feldspar, zeolites mica, and asbestos...

The basic structural unit of feldspar, zeolites mica, and asbestos is:

Options

A ${\left(Si{O}_{4}\right)}^{4 -}$
B
C ${\left(Si{O}_{3}\right)}^{2 -}$
D $Si{O}_{2}$

Correct answer

A. ${\left(Si{O}_{4}\right)}^{4 -}$

Step-by-step solution

Feldspars are a group of rock-forming tectosilicate minerals.
Mica minerals are phyllosilicate compounds.
Zeolites are a large group of minerals consisting of hydrated aluminosilicates of Sodium, Potassium, Calcium and Barium.
Thus, it is evident that Silicates are the basic component in Feldspars, Mica, Zeolites and Asbestos and have

{Si{O}_{4}}^{4 -}

basic unit.
