Discuss the basic unit and structure of silicates. |
Answer» Solution :Silicates are the compounds in which the anions are present as either DISCRETE `SiO_(4)^(4-)` tetrahedral or a number of such UNITS joined together through corners. Silicates are basically made up `SiO_(4)^(4-)` tetrahedra ( as shown in the figure ) in which SILICON atom is bonded to four OXYGEN atoms in a tetrahedral MANNER. In the figure big circles indicate oxygen atoms and samall circle indicates silicon atoms.
