Detailed explanation-1: -silicate mineral structures is the silicon-oxygen tetrahedron (SiO4)4-. It consists of a central silicon atom surrounded by four oxygen atoms in the shape of a tetrahedron.
Detailed explanation-2: -Sheet silicates are formed when three oxygen atoms (bridging O-atoms) of each (SiO4)4− unit are shared. Was this answer helpful?
Detailed explanation-3: -abbreviated Si-O tetrahedron). It consists of one silicon cation (Si-4) surrounded by 4 oxygen. anions (O-2) in a 4-sided pyramid arrangement known as a tetrahedron.
Detailed explanation-4: -Linear chain silicates have 2 oxygen atoms shared. Sheet silicate is the one where 3 oxygen atoms are shared. If all the four oxygen atoms if the [SiO4]− units are shared – they are called three-dimensional silicates.
