![]() Atomic clocks: Cesium-133 is used as a reference for atomic clocks, which are the most accurate time-keeping devices available today.Use of cesiumĬesium has a variety of uses and applications in science, technology, and medicine, including: However, due to its reactivity and potential health hazards, cesium must be handled with care and proper safety precautions. Overall, cesium’s high reactivity and unique chemical properties make it a valuable element for various applications in science and technology. Cesium-137, a radioactive isotope, has important applications in scientific research and in the medical field for radiation therapy. Isotopes: Cesium has 39 known isotopes, but only one stable isotope, cesium-133.Some of the most important cesium compounds include cesium chloride, cesium carbonate, and cesium nitrate. Chemical compounds: Cesium can form a variety of chemical compounds, including halides, carbonates, nitrates, and sulfates.Electronegativity: Cesium is one of the most electropositive elements, which means that it readily gives up its valence electron in chemical reactions.This means that cesium loses one electron to form a positive ion when it reacts with other elements. Oxidation states: Cesium has only one stable oxidation state, which is +1.It also reacts vigorously with other substances, such as halogens and acids. ![]() It reacts explosively with water to produce hydrogen gas and a solution of cesium hydroxide. Reactivity: Cesium is the most reactive metal of all the alkali metals.Here are some of its chemical properties: Overall, cesium has unique physical properties, such as its low melting point, low boiling point, and high reactivity, that make it a valuable element for various applications in science and technology. It also reacts vigorously with many other substances, such as halogens and acids. Reactivity: Cesium is one of the most reactive elements, and reacts explosively with water to produce hydrogen gas and a solution of cesium hydroxide.Electrical conductivity: Cesium is a good conductor of electricity, and its conductivity is the highest of all metals except for silver and copper.Atomic radius: Cesium has the largest atomic radius of all elements in the periodic table, due to the relatively low effective nuclear charge experienced by its valence electron.Density: Cesium is one of the least dense metals, with a density of 1.93 grams per cubic centimeter.Melting and boiling point: Cesium has a low melting point of 28.5 ☌ (83.3 ☏) and a low boiling point of 671 ☌ (1,240 ☏).State: Cesium is a soft, silvery-gold metal that is liquid at or near room temperature.Here are some of its physical properties:
