it is the most electropositive strong basic element. An explosion occurred in reaction with cold water. At -116 °c, it can still react with water. Soluble in liquid ammonia, the formation of amino compounds and hydrogen. It can directly react with halogen, phosphorus and sulfur to generate...
One of the most intriguing characteristics of caesium is its extreme reactivity to air and water. When exposed to air, it rapidly reacts to form a layer of caesium oxide on its surface. Similarly, when it comes into contact with water, it vigorously reacts,producing caesium hydroxide and hyd...
Caesium was discovered by Robert Bunsen and Gustav Kirchhoff (Germany) in 1860. The origin of the name comes from the Latin wordcaesiusmeaningsky blueorheavenly blue. It is very soft, light grey, ductile metal. Reacts readily with oxygen. Reacts explosively with water. Caesium is found in ...
Caesium metal is highly reactive and pyrophoric. It ignites spontaneously in air, and reacts explosively with water even at low temperatures, more so than the other alkali metals.[12] It reacts with ice at temperatures as low as −116 °C (−177 °F).[16] Because of this high react...
Isolated caesium is extremely reactive and very pyrophoric. In addition to igniting spontaneously in air, it reacts explosively with water (even cold), even more so than the other members of the first group of the periodic table.[note 3] The reaction with solid water occurs even at temperatur...
it is pyrophoric and reacts with water even at −116 °C (−177 °F). It is the least electronegative element, with a value of 0.79 on the Pauling scale. It has only one stable isotope, caesium-133. Caesium is mined mostly from pollucite, while the radioisotopes, especially caesium...

However, this compound is not usually used in experiments as the extraction of caesium is very expensive and the fact that it behaves very much like rubidium hydroxide and potassium hydroxide but reacts chemically stronger than they do.
It is a very soft, light grey, ductile metal that reacts readily with oxygen and reacts explosively with water. Caesium is found in pollucite [(Cs4Al4Si9O26).H2O] and as trace in lepidolite. It is used as a 'getter' to remove air traces in vacuum and cathode-ray tubes, in ...
