Facts about Cesium
Facts about Cesium - Element included on the Periodic Table
Facts about the Definition of the Element Cesium (Caesium spelt as Cesium in the USA)
The Element Cesium is defined as...
A soft, silvery-white ductile metal, liquid at room temperature, the most electropositive and alkaline of the elements, used in photoelectric cells and to catalyze hydrogenation of some organic compounds. The most common uses of Cesium are in Atomic clocks, Removing air traces in vacuum tubes, Ion propulsion systems, Medical, Photoelectric cells, Cesium vapor and the Magnetometer.
Interesting Facts about the Origin and Meaning of the element name Cesium
What are the origins of the word Caesium ?
The word Caesium originates from the Latin word 'caesius' which means "sky blue" from the bright blue lines in its spectrum.
Facts about the Classification of the Element Cesium
Cesium is classified as an "Alkali Metal" and located in Group 1 elements of the Periodic Table. An Element classified as an Alkali Metal is a very reactive metal that does not occur freely in nature. Alkali metals are soft, malleable, ductile, and are good conductors of heat and electricity.
Brief Facts about the Discovery and History of the Element Cesium
Cesium was discovered by Fustov Kirchoff and Robert Bunsen in 1860 from mineral water found in Durkheim, Germany. It was the first element discovered by spectrum analysis.

Facts and Info about the element Cesium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 which includes the Cesium element. The famous Russian Scientist, Dimitri Mendeleev, perceived the correct classification method of "the periodic table" for the 65 elements which were known in his time. Cesium was discovered by Fustov Kirchoff and Robert Bunsen in 1860 from mineral water found in Durkheim, Germany. It was the first element discovered by spectrum analysis. The Standardised Periodic Table now recognises more periods and elements than Dimitri Mendeleev knew in his day but still all fitting into his concept of the "Periodic Table" in which Cesium is just one element that can be found.
