TY - JOUR TI - Westium and Ruthenium against the background of the history of chemistry AU - Lichocka, Halina TI - Westium and Ruthenium against the background of the history of chemistry AB - Is the chemical element Vestium discovered by Jędrzej Śniadecki the same as the Ruthenium? The dispute on this subject has been going on for more than one hundred years. At present, this dispute over recognition of the priority of discovery is very difficult to resolve. However, from the point of view of the history of chemistry, another aspect is more important in all this. In this context, it turns out that Jędrzej Śniadecki was the first researcher who tried to prove the existence of the sixth platinum metal. Time showed that Śniadecki was right. The confirmation of this was the subsequent separation of the metallic ruthenium by Karl Ernst Claus.
