Element Caesium (Cs), Group 1, Atomic Number 55, s-block, Mass 132.905. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.
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]
With an electron in the sixth and outermost shell, cesium is the most electropositive of all stable elements in the periodic table: the metal is extremely pyrophoric, ignites spontaneously when in contact with air, and explodes violently in water or ice at any temperature above -116 ° C.
28 cze 2024 · Cesium, often symbolized as Cs, is a soft, silvery-gold alkali metal with atomic number 55. It’s known for its high reactivity and low melting point. This element is used in various industries, including electronics, atomic clocks, and even as a catalyst in the hydrogenation of certain organic compounds.
Significance and Uses. Caesium is used in vacuum tubes as a “getter” to clean the traces of oxygen and other gases when sealed. Caesium compounds with chlorides are used in photoelectric cells. Caesium is used in industries as a catalyst promoter. Caesium nitrate is used to make optical glasses.
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.
