Facts about the Classification of the Element Roentgenium Rubidium 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 Roentgenium Rubidium was discovered by Robert Bunsen and Gustav Kirchhoff in 1861 in the mineral lepidolite through the use of a spectroscope. It has the highest room temperature conductivity of any known ionic crystal. Ignites spontaneously in air. Reacts violently in water. |
Occurrence of the element Roentgenium in the Atmosphere Obtained from lithium production 16th most abundant element in the earth's crust Occurs naturally in the minerals leucite, pollucite, and zinnwaldite |
Common Uses of Roentgenium Research and development in chemical and electronic applications Catalyst Photocells Fireworks Vapour turbines Rubidium chloride |

Facts and Info about the element Argon - 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 Roentgenium 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. Rubidium was discovered by Robert Bunsen and Gustav Kirchhoff in 1861. 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 Roentgenium is just one element that can be found. |
