Answer» Solution :FELDSPAR, ZEOLITES, mica and asbestos are SILICATES minerals. The basic structural unit of silicates is `SiO_4^(4-)`(Refer Fig.) in which silicon atom is bonded to four oxygen atoms in tetrahedron fashion. In silicate compound, atoms are joined together via corners by sharing 1, 2, 3, 4 or 4 oxygen. When silicate units are linked together, they form chain, ring, sheet or three-dimensional structures. Negative charge on silicate structure is neutralised by positively charged metal ions. Two important man-made silicates are glass and cement.
