    Which silicates is formed from \[SiO_{4}^{4-}\]tetrahedral units by sharing three oxygen atoms?

    A) Sheet silicates

    B) Pyro silicates

    C) Linear chain silicates

    D) Three dimensional silicates

    Correct Answer: A

    Solution :

    [a] : The sharing of three corners i.e., three oxygen of each tetrahedron \[(SiO_{4}^{4-})\] results in an infinite two dimensional sheet structure of the formula \[(S{{i}_{2}}{{O}_{5}})_{n}^{2n-}\].
