The basic structural unit in silicates is

About 95 % of the eath's crust is composed of silicated minerals, aluminosilicate clays, or silica. The majority of silicate minerals are very insoluble, because they have an infinite ionic structure and because of the great strength of the Si - O bond. the basic structural units of silicate is (sIO_(4))^(4-) tetrahedra. The (SiO_(4))^(4-) tetrahedral may polymerize in to large units by sharing atoms Pyllo-silicates are formed by the sharing of the O atoms on...... corners of each tetrahedron with other tetrahedral
