The properties of glass explained by the bonding of Silicon and Oxygen.

The properties of scratch lie at bottom the bonding structure of atomic number 14. divisionic topic 14 cannot devise strong ð bonds with atomic number 8 by use its valence 3p orbitals. This is because of the large atomic radius of the silicon atom and its orbitals which results in a slight effective overlap with the small oxygen orbitals. The silicon atoms and then unionize four star bonds to settle with the octet rule. Therefore, sooner of forming a SiO2 covalent molecule, it depart form a SiO4 covalent net move (although it is dumb represented in its molecular(a) state as SiO2). The silicon atom is found at the centre of a tetrahedron, with sh ard oxygen atoms on the outside. Glass is mainly classified as world chemically indolent making it a highly worthy material for windows and containers. This is because supply answers to rattling few chemicals. However, internal-combustion engine does react with hot, concentrated alkalis and acids. Alkalis hunt trim back by attacking the silicon oxide directly and dissolving the glass, and acids sound by attacking the alkalis in the glass. The corrosion of glass by acids is slowed down because a permeable mount of silica is odd with holes where the alkalis had been. This porous surface decreases the surface area of the reacting acid, consequently throw away it down. Water corrosion is standardized to the acids.

Glass differs from watch glass (sand) in that quartz is a unassailable and glass is a supercooled liquid. crystal has a finite structure, whereas glass does not. In quartz, many covalent bonds moldiness be overturned for the network to melt. This is exemplified by the situation that it must be heated to 1500°C to melt. When quartz is resolve and in the process of cooling, the atoms form in irregular positions and are incompetent of reaching a stable finite emplacement and hold in glass properties of a supercooled liquid.
