Caesium hydroxide is a strong base (pK a = 15.76) containing the highly reactive alkali metal caesium, much like the other alkali metal hydroxides such as sodium hydroxide and potassium hydroxide. It is the strongest of the five alkali metal hydroxides. [ 7 ]
This page shows the electron configurations of the neutral gaseous atoms in their ground states. For each atom the subshells are given first in concise form, then with all subshells written out, followed by the number of electrons per shell.
[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
The hydroxyl radical, Lewis structure shown, contains one unpaired electron. Lewis dot structure of a Hydroxide ion compared to a hydroxyl radical. In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron.
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. [ 3 ]
They consist of hydroxide (OH −) anions and metallic cations, [1] and are often strong bases. Some metal hydroxides, such as alkali metal hydroxides, ionize completely when dissolved. Certain metal hydroxides are weak electrolytes and dissolve only partially in aqueous solution.

Caesium superoxide's crystal structure is same as calcium carbide. It contains direct oxygen-oxygen bonding. [2] It reacts with water to form hydrogen peroxide and caesium hydroxide. [2] 2 CsO 2 + 2 H 2 O → O 2 ↑ + H 2 O 2 + 2 CsOH. Heating to approximately 400 °C induces thermal decomposition to caesium peroxide. [3]
