He also invented the spectroscope and with it discovered rubidium and caesium greatly perfected methods of electrolysis, inventing a new battery made many investigations among metallic and organic substances.Ĭheck out Cesium on the Periodic Table which arranges each chemical element according to its atomic number, as based on the Periodic Law, so that chemical elements with similar properties are in the same column. ![]() Robert Wilhelm Bunsen (1811-1899) invented many lecture-room and laboratory appliances, most famously the Bunsen burner. It was the first element discovered by spectrum analysis.

Alkali metals are soft, malleable, ductile, and are good conductors of heat and electricity. An Element classified as an Alkali Metal is a very reactive metal that does not occur freely in nature. Cesium is classified as an "Alkali Metal" and located in Group 1 elements of the Periodic Table. What is Cesium? Periodic Table Group and Classification of the Cesium ElementĮlements can be classified based on their physical states (States of Matter) e.g. The word Caesium originates from the Latin word 'caesius' which means "sky blue" from the bright blue lines in its spectrum.
