\(Si_2O_7^{-6}\) anion is obtained when
1 no oxygen of a \(SiO_4\) tetrahedron is shared with another \(SiO_4\) tetrahedron
2 one oxygen of a \(SiO_4\) tetrahedron is shared with another \(SiO_4\) tetrahedron
3 two oxygen of a \(SiO_4\) tetrahedron are shared with another \(SiO_4\) tetrahedron
4 three or all four oxygen of a tetrahedron are shared with other \(SiO_4\) tetrahedron
Explanation:
\(Si _2 O _7^{6-}\) anion is obtained when one oxygen of a \(SiO _4\) tetrahedron is shared with another \(SiO _4\) tetrahedron.
