Question

describe silicones, silicates and zeolite;
​

Answer 1

Answer:

Silicones are a type of synthetic polymer, a material made of smaller, repeating chemical units called monomers that are bonded together in long chains. Silicone consists of a silicon-oxygen backbone, with “sidechains” consisting of hydrogen and/or hydrocarbon groups attached to the silicon atoms. A silicate mineral is generally an ionic compound whose anions consist predominantly of silicon and oxygen atoms. In most minerals in the Earth's crust, each silicon atom is the center of an ideal tetrahedron, whose corners are four oxygen atoms covalently bound to it. Zeolites are three-dimensional, microporous, crystalline solids with well-defined structures that contain aluminium, silicon, and oxygen in their regular framework; cations and water are located in the pores. The silicon and aluminium atoms are tetrahedrally coordinated with each other through shared oxygen atoms.

Answer 2

Answer:

A big number of silicates unit exists which are zeolites etc.

The structure of silicate is SiO44-, in which the four oxygen atom is attached to one silicon atom.

When silicate unit is joined together it forms ring, chain as well as 3-D structure. Glass and cement are two important silicates that are man-made.
