The chemistry of caesium is similar to that of other alkali metals, in particular rubidium, the element above caesium in the periodic table. [28] As expected for an alkali metal, the only common oxidation state is +1. It differs from this value in caesides, which contain the Cs − anion and thus have caesium in the −1 oxidation state. [5]
Carbon monosulfide is a chemical compound with the formula CS. This diatomic molecule is the sulfur analogue of carbon monoxide, and is unstable as a solid or a liquid, but it has been observed as a gas both in the laboratory and in the interstellar medium. [1] The molecule resembles carbon monoxide with a triple bond between carbon and sulfur.
The compound 2-chlorobenzalmalononitrile (also called o-chlorobenzylidene malononitrile; chemical formula: C 10 H 5 ClN 2), a cyanocarbon, is the defining component of the lachrymatory agent commonly referred to as CS gas, a tear gas which is used as a riot control agent, and is banned for use in warfare due to the 1925 Geneva Protocol.
Carbon disulfide (also spelled as carbon disulphide) is an inorganic compound with the chemical formula CS 2 and structure S=C=S. It is also considered as the anhydride of thiocarbonic acid . [ 8 ] It is a colorless, flammable, neurotoxic liquid that is used as a building block in organic synthesis.
Caesium carbonate or cesium carbonate is a chemical compound with the chemical formula Cs 2 C O 3.It is white crystalline solid. Caesium carbonate has a high solubility in polar solvents such as water, ethanol and DMF.
Caesium oxide (IUPAC name), or cesium oxide, describes inorganic compounds composed of caesium and oxygen.Several binary (containing only Cs and O) oxides of caesium are known.
Similar to sodium sulfide, anhydrous cesium sulfide can be produced by reacting cesium and sulfur in THF.It needs ammonia or naphthalene to react. [4]2 Cs + S → Cs 2 S. By dissolving hydrogen sulfide into cesium hydroxide solution, it will produce cesium bisulfide, then it will produce cesium sulfide too.
Caesium sulfate or cesium sulfate is the inorganic compound and salt with the formula Cs 2 SO 4. It is a white water-soluble solid that is used to prepare dense aqueous solutions for use in isopycnic (or "density-gradient") centrifugation. It is isostructural with potassium salt. [3]
