Caesium is a metal denoted as Cs in the period table with the atomic number of 55. It is one of the most reactive metal. It is found in the s-block which is because the outermost electron of Caesium is in s-orbital. Caesium is a soft, shiny-gold alkali metal which is having a melting point of 28.5 ┬░Celsius (83.3 ┬░Fahrenheit), which is one of five rudimentary metals that can become liquid at room temperature.

The Discovery of Caesium

Chemists such as Robert Bunsen and Gustav Kirchhoff who discovered cesium in 1860 when investigating the spectrum in mineral water. The name designated from the Latin word "caesius", which denotes "sky blue". This defines to the color of the line that the spectrum the chemists saw when they were discovering the spectrum. This later on tipped them of a new element caesium.

Possessions of Caesium

Samples of cesium are kept in sealed containers, under an inert liquid or gas or in a vacuum. The element is highly reactive that it would react with water and air.

Cesium instinctively ignites in air which describes that it is pyrophoric in nature.

It is the one of the supreme alkaline of all the elements and oxidizes explosively with water to give rise to caesium hydroxide (CsOH), which is a strong base in nature.

Allen scale of electronegativity indicates cesium as the most electronegative element.

It is drawn into fine wires because of its softer-ductile character.

Cesium-133 is the only one isotope of cesium that occurs naturally. Although there are numerous radioactive isotopes that has been produced.

Caesium atom has an electron resonance frequency of 9,192,631,770 cycles per second.
