31 sie 2016 · Cesium is a rare, silver-white, shiny metal with brilliant blue spectral lines; the element's name comes from "caesius," a Latin word meaning "sky blue." It is the softest metal, with a...
9 paź 2024 · cesium (Cs), chemical element of Group 1 (also called Group Ia) of the periodic table, the alkali metal group, and the first element to be discovered spectroscopically (1860), by German scientists Robert Bunsen and Gustav Kirchhoff, who named it for the unique blue lines of its spectrum (Latin caesius, “sky-blue”).
Cesium, represented by the atomic number 55 and symbol "Cs," is an alkali metal that is soft, silvery-gold in color, and highly reactive. The element is known for its applications in atomic clocks, medical treatments, and a variety of industrial processes.
Caesium or cesium is a chemical element with symbol Cs and atomic number 55. It is a soft, silvery-gold Alkali Metal with a melting point of 28 °C (82 °F), which makes it one of only five elemental metals that are liquid at or near room temperature.
Cesium is a soft, silvery-white alkali metal that is the most electropositive and reactive of all the stable elements. It is the least dense of the stable elements and has the highest electron affinity of any element, making it highly reactive and prone to forming ionic compounds.
Cesium is an extremely reactive metal and the most alkaline of the elements. It reacts explosively upon contact with water producing cesium hydroxide (CsOH), an extremely strong base that can rapidly corrode glass.
