The compound reacts violently with water, yielding caesium hydroxide, metallic gold, and hydrogen gas; in liquid ammonia it can be reacted with a caesium-specific ion exchange resin to produce tetramethylammonium auride. The analogous platinum compound, red caesium platinide (Cs 2 Pt), contains the platinide ion that behaves as a ...
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
Caesium-137 reacts with water, producing a water-soluble compound (caesium hydroxide). The biological behaviour of caesium is similar to that of potassium [16] and rubidium. After entering the body, caesium gets more or less uniformly distributed throughout the body, with the highest concentrations in soft tissue.

The alkali metals also react with water to form strongly alkaline hydroxides and thus should be handled with great care. The heavier alkali metals react more vigorously than the lighter ones; for example, when dropped into water, caesium produces a larger explosion than potassium if the same number of moles of each metal is used.
An important application of caesium iodide crystals, which are scintillators, is electromagnetic calorimetry in experimental particle physics.Pure CsI is a fast and dense scintillating material with relatively low light yield that increases significantly with cooling, [11] and a fairly small Molière radius is 3.5 cm.
Caesium hydride or cesium hydride is an inorganic compound of caesium and hydrogen with the chemical formula Cs H.It is an alkali metal hydride.It was the first substance to be created by light-induced particle formation in metal vapor, [2] and showed promise in early studies of an ion propulsion system using caesium.
