Topic Name : Some Important Compounds Of Carbon And Silicon |
|
Sub Topic Name : Silicates |
1.A large number of silicates minerals exist in nature. Some of the examples are feldspar, zeolites, mica and asbestos. 2.The basic structural unit of silicates is SiO4 4– in which silicon atom is bonded to four oxygen atoms in tetrahedron fashion. 3.In silicates either the discrete unit is present or a number of such units are joined together via corners by sharing 1,2,3 or 4 oxygen atoms per silicate units. 4.When silicate units are linked together, they form chain, ring, sheet or three-dimensional structures. 5.Two important man-made silicates are glass and cement.
