Oxidation of silicon to create a silicon dioxide layer on the silicon surface can be done either by the thermal growth methods or the undesired native growth process. there are two for silicone.those are 0 and 4.Atomic silicon has oxidation number 0. Volume number: Issue number (if known): Article or page number: Journal of Physics: Condensed Matter. The Oxidation state of Silicon (Si) is +2, with atomic number 14. The process is an adding procedure which adds oxygen to react with silicon to form silicon dioxide on the silicon surface. Plasma oxidation. H is +1. … The reason the most common oxidation states of silicon are positive is because most elements that silicon forms compounds with are of greater electronegativity than silicon (e.g. The limited number of silicon atoms that can catenate, however, greatly reduces the number and variety of silicon compounds compared with those of carbon. The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic, with no covalent component. It is relatively inactive at ordinary temperatures, when heated it reacts vigorously with the halogens to form halides and with certain metals it forms silicides. To find the correct oxidation state of S in SO2 (Sulfur dioxide), and each element in the molecule, we use a few rules and some simple math.
