When there is no public data on the element in its pure form, price of a compound is used, per mass of element contained. This implicitly puts the value of compounds' other constituents, and the cost of extraction of the element, at zero. For elements whose radiological properties are important, individual isotopes and isomers are listed. The ...
Cs 2 CO 3 + HN 3 → CsN 3 + CO 2 + H 2 O. Caesium sulfate reacts with barium azide to form insoluble barium sulfate and caesium azide: Cs 2 SO 4 + Ba(N 3) 2 → 2CsN 3 + BaSO 4 ↓. The thermal decomposition of CsN 3 in vacuo can be used as a method of generating high purity caesium metal: [5] 2 CsN 3 → 2 Cs + 3 N 2
Caesium (IUPAC spelling; [9] also spelled cesium in American English) is a chemical element; it has symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F; 301.6 K), which makes it one of only five elemental metals that are liquid at or near room temperature .
Caesium ozonide is an oxygen-rich chemical compound of caesium, with the chemical formula Cs O 3. It consists of caesium cations Cs + and ozonide anions O − 3. It can be formed by reacting ozone with caesium superoxide: [2] [3] CsO 2 + O 3 → CsO 3 + O 2. The compound reacts strongly with any water in the air forming caesium hydroxide. [3] 4 ...
The best performance (in terms of thrust efficiency and power-to-thrust ratio) can be obtained using high atomic weight alkali metals, such as cesium (Cs, 133 amu) and rubidium (Rb, 85.5 amu). These propellants have a low ionization potential (3.87 eV for Cs and 4.16 eV for Rb), low melting point (28.7 °C for Cs and 38.9 °C for Rb) and very ...
Cesium cyanide (chemical formula: CsCN) is the cesium salt of hydrogen cyanide. It is a white solid, easily soluble in water, with a smell reminiscent of bitter almonds, and with crystals similar in appearance to sugar. Caesium cyanide has chemical properties similar to potassium cyanide and is very toxic.

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. [5] [6] 。 CsOH + H 2 S → CsHS ...
