Cesium is a fascinating element with a range of uses and applications, from the intricacies of time-keeping in atomic clocks to radiation therapies for cancer treatments. Its highly reactive nature makes it dangerous but also uniquely suitable for specific applications that require such reactivity.
Element Caesium (Cs), Group 1, Atomic Number 55, s-block, Mass 132.905. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.
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.
Cesium is used as an atomic resonance frequency standard in atomic clocks, playing a vital role in global positioning satellites, Internet, and cellular telephone transmissions and aircraft guidance systems.
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.

Cesium is a very reactive metal. It combines quickly with oxygen in the air and reacts violently with water. In the reaction with water, hydrogen gas is released. Hydrogen gas ignites immediately as a result of the heat given off by the reaction.
