Silicates

About 95% of the earth's crust is composed of silicate minerals, alumino silicate clay r silica. Silicates are classified on the basis of bonding and the metal ions present in them. Some of the common categories of silicates are (I) orthosilicates , (II) pyrosilicates (III) cyclic silicates , (IV) chain silicates (V) amphiboles , (VI) sheet silicates (VII) three-dimensional network silicates What is true regarding a double chain silicate 'Amphiboles' ?

One of the calcium silicates is called Wollastonite. The silicate present in the mineral has a plane projection structure as follows. What is the positive charge that has to be provided to compensate the negative charge of silicate.
