Etymology: Karl Ernst Claus, a Baltic German chemist working in Russia, isolated this metal in 1844 from platinum ore, and he named it after Ruthenia, the Latin name for Russia. The choice was a tribute to his adopted country, which was then the source of the platinum he was studying. The "-ium" ending follows the convention chemists used for newly identified elements, borrowed from the Latin neuter suffix that gives metals like "sodium" and "calcium" their form. Attaching it to "Ruthenia" produced a name that sounds like a classical metal but is simply a geographic label. Ruthenia itself was a Latin term for the lands of the East Slavs, and it survives in the name of the region of Ruthenia in Central Europe. The metal therefore carries an old Latin map name rather than a mythological or descriptive one.
