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.
The element is known for its applications in atomic clocks, medical treatments, and a variety of industrial processes. As an alkali metal, it is extremely reactive and must be handled with care, stored in inert atmospheres, and isolated from water.
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 is a silvery-gold metallic element. It is an extremely soft metal. Caesium is one of four elements who exist in liquid form at or near room temperature. In periodic table it belongs to alkaline elements. Its physical properties are similar with rubidium and potassium. In the presence of mineral oil it loses its metallic luster.
29 cze 2023 · It is a soft, silvery-golden alkali metal and belongs to the s-block of group 1 of the periodic table. This material has a low melting point of 28 degrees Celsius (83 degrees Fahrenheit), which makes it one of the metals that are liquid at or close to room temperature.
Both cesium and its compounds find practical uses. Cesium metal can be used as a getter to remove oxygen in phototubes. It is used in atomic clocks that are accurate to within five seconds per every three hundred years. (A second is defined as 9,192,631,770 oscillations of a Cs-133 atom.)
