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. [1] [2] Caesium oxide may refer to: Caesium suboxides (Cs 7 O, Cs 4 O, and Cs 11 O 3) Caesium monoxide (Cs 2 O, the most common oxide) Caesium peroxide (Cs 2 O 2 ...
Caesium monoxide or caesium oxide is a chemical compound with the chemical formula Cs 2 O. It is the simplest and most common oxide of the caesium . It forms yellow-orange hexagonal crystals.
Caesium has physical and chemical properties similar to those of rubidium and potassium. It is pyrophoric and reacts with water even at −116 °C (−177 °F). It is the least electronegative stable element, with a value of 0.79 on the Pauling scale. It has only one stable isotope, caesium-133. Caesium is mined mostly from pollucite.
Caesium peroxide or cesium peroxide is an inorganic compound of caesium and oxygen with the chemical formula Cs 2 O 2. It can be formed from caesium metal by adding a stoichiometric amount in ammonia solution, or oxidizing the solid metal directly. [1] 2 Cs + O 2 → Cs 2 O 2. It can also be formed by the thermal decomposition of caesium ...
Caesium sesquioxide is a chemical compound with the formula Cs 2 O 3 or more accurately Cs 4 O 6. It is an oxide of caesium containing oxygen in different oxidation states. It consists of caesium cations Cs +, superoxide anions O − 2 and peroxide anions O 2− 2. Caesium in this compound has an oxidation state of +1, while oxygen in ...
Caesium superoxide is a chemical compound with the chemical formula CsO 2. It consists of caesium cations Cs + and superoxide anions O − 2 . It is an orange solid.
It breaks down into manganese dioxide, caesium oxide and oxygen. [5] The decomposition temperature is between 200 and 300 °C. [6] Drift-away oxygen caused an 8% mass loss in the product. [6] 10CsMnO 4 → 3Cs 2 MnO 4 + 7MnO 2 + 2Cs 2 O + 6O 2 ↑ 2Cs 2 MnO 4 → 2MnO 2 + 2Cs 2 O + O 2 ↑. Total reaction: 4CsMnO 4 → 4MnO 2 + 2Cs 2 O + 3O 2 ↑
