Vedclass · Answer

(A) In a $SiO_4^{4-}$ tetrahedron,there are $4$ oxygen atoms.- In sheet silicates,$3$ oxygen atoms are shared,leaving $1$ oxygen atom unshared (monovalent).- In cyclic silicates,$2$ oxygen atoms are shared,leaving $2$ oxygen atoms unshared.- In single chain silicates,$2$ oxygen atoms are shared,leaving $2$ oxygen atoms unshared.- In double chain silicates,some tetrahedra share $2$ and some share $3$ oxygen atoms.Since sheet silicates have $3$ shared oxygen atoms per tetrahedron,they possess $1$ monovalent (unshared) oxygen atom per unit.Therefore,the correct option is $A$.
