The preparation method of silicon from silica sand and purification method of silicon needs to be explained. Concept introduction: The group 4A elements show variation from non-metals to metals down in the group. The first element of the group 4A is carbon with 4 valence electrons. Since Si has four valence electrons therefore it shows tetravalency and can form four covalent bonds with same or different elements. Because of the tetravalency nature, Si tends to form covalent bonds with same or different elements to form a large number ofchemical compounds.
