Silicon monoxide is the chemical compound with the formula SiO where silicon is present in the oxidation state +2. In the vapour phase, it is a diatomic molecule. [1] It has been detected in stellar objects [2] and has been described as the most common oxide of silicon in the universe.
[4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond. Lewis structures show each atom and its position in the structure of the molecule using its chemical symbol.
A less common oxide is silicon monoxide that can be found in outer space. Unconfirmed reports exist for nonequilibrium Si 2 O, Si 3 O 2, Si 3 O 4, Si 2 O 3 and Si 3 O 5. [94] Silicon sulfide is also a chain compound. Cyclic SiS 2 has been reported to exist in the gas phase. [95] The phase diagram of silicon with selenium has two phases: SiSe 2 ...
The following tables list molecules that have been detected in the interstellar medium or circumstellar matter, grouped by the number of component atoms.Neutral molecules and their molecular ions are listed in separate columns; if there is no entry in the molecule column, only the ionized form has been detected.
Silicon compounds are compounds containing the element silicon (Si). As a carbon group element, silicon often forms compounds in the +4 oxidation state , though many unusual compounds have been discovered that differ from expectations based on its valence electrons , including the silicides and some silanes .

Silicon oxide may refer to either of the following: Silicon dioxide or quartz, SiO 2 , very well characterized Silicon monoxide , SiO, not very well characterized
Silicon is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive.
