Select the correct statement about silicates: — p Block Elements Chemistry Question

💡 Solution & Explanation

[SEE DIAGRAM] Cyclic silicate having three Si atoms (Si3O9^6-) contains three Si—O—Si linkage. Double chain silicates: One tetrahedron shares three oxygen atoms while other share two oxygen atoms, these two tetrahedrons constitute one unit. Therefore, no. of oxygen atoms shared per tetrahedron = (3+2)/2 = 2.5
