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.
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 .
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.
When the electropositive element is a metal, the compounds are sometimes referred to as “metal-rich”. Thus the normal oxide of caesium is Cs 2 O, which is described as a Cs + salt of O 2−. A suboxide of caesium is Cs 11 O 3, where the charge on Cs is clearly less than 1+, but the oxide is still described as O 2−.
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

The 2-year-old girl's body temperature was found to be as high as 109.4 degrees Fahrenheit, according to police Parents Accused of Leaving Toddler in Closet Overnight with Space Heater On. She Was ...
Conversely, while the S N 2 reaction is mostly unaffected by the presence of a partial positive charge (δ+) at the carbon, the analogous "S N 2" reaction at silicon is so affected. Thus, for example, the silyl triflates are so electrophilic that they react 10 8 to 10 9 times faster than silyl chlorides with oxygen-containing nucleophiles.
