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 .
Cesium salts are used as catalysts and for the production of special glasses and ceramics. In molecular biology, they are applied for decades for density gradient ultracentrifugation in order to isolate viral particles, subcellular organelles and fractions, and nucleic acids from biological samples.
9 paź 2024 · Cesium is the most electropositive and most alkaline element, and thus, more easily than all other elements, it loses its single valence electron and forms ionic bonds with nearly all the inorganic and organic anions.
Cesium, Physical and Chemical Properties. Cesium is a very soft, ductile, silvery white metal. It is the last member of the alkali metals (if Francium, the metal following it in the group, is ignored since it is radioactive with very short half-life).
Cesium is a very reactive metal. It combines quickly with oxygen in the air and reacts violently with water. In the reaction with water, hydrogen gas is released. Hydrogen gas ignites immediately as a result of the heat given off by the reaction.
