28 cze 2024 · Molecular Structure: Soft, silvery-gold alkali metal. Electron Configuration: 55 electrons, with the configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 6s¹. Significance: Cesium is used in atomic clocks, photoelectric cells, and in the oil industry as a drilling fluid.
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.
Caesium, also spelt as Cesium, was discovered in 1860. It is outstanding in keeping time with precision, so it is used in atomic clocks. It forms alloys with alkali metals, gold and mercury. History and Discovery. Caesium is considered the first element who was discovered spectroscopically in 1860 by Robert Bunsen and Gustav Kirchhoff.
