28 cze 2024 · Cesium, a fascinating element on the periodic table, plays a crucial role in various applications. This guide delves into its intriguing properties and practical uses, offering a comprehensive understanding for teachers and students alike.
Caesium vapour is used in many common magnetometers. [91] The element is used as an internal standard in spectrophotometry. [92] Like other alkali metals, caesium has a great affinity for oxygen and is used as a "getter" in vacuum tubes. [93] Other uses of the metal include high-energy lasers, vapour glow lamps, and vapour rectifiers. [14]
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”).
Caesium is the most electropositive, most alkaline and has the least ionization potential of all the elements. Known uses include the basis of atomic clocks, catalyst for the hydrogenation of some organic compounds, and in photoelectric cells.
