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.

Instead, most form eutectic mixtures, although the heaviest stable ones – mercury, thallium, lead, and bismuth – are completely immiscible with liquid silicon. [2] Usually, silicides are prepared by direct reaction of the elements. For example, the alkali metals and alkaline earth metals react with silicon or silicon oxide to give silicides ...
A silicon–oxygen bond (Si−O bond) is a chemical bond between silicon and oxygen atoms that can be found in many inorganic and organic compounds. [1] In a silicon–oxygen bond, electrons are shared unequally between the two atoms , with oxygen taking the larger share due to its greater electronegativity .
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 ...
Suboxides are a class of oxides wherein the electropositive element is in excess relative to the “normal” oxides. [1] When the electropositive element is a metal, the compounds are sometimes referred to as “metal-rich”.
Silylidyne is a chemical substance occurring as a molecule found in stars and probably existing in interstellar space, or as a monolayer on the surface of solid silicon. The SiH molecule is a radical , and can be made experimentally by striking an electric arc to silicon on a low pressure hydrogen gas.
