masurium

Masurium (symbol Ma) was a name proposed for chemical element 43, which was eventually named technetium. Two of the discoverers of rhenium, Walter Noddack and Ida Tacke claimed to have at the same time (1925) discovered this element which they named after Masuria in Eastern Prussia, the region where Walter Noddack's family originated. Their claim of dicovery was not generally accepted, and so the element was eventually named by the Italian chemists Carlo Perrier and Emilio Segr who had detected in a sample of molybdenum that had been bombarded with deuterium nuclei. Recently, work by John T. Armstrong at NIST suggests that the Noddacks had indeed discovered element 43, but it is extremely unlikely that even if this view were to be widely accepted that their proposed name would be adopted at this late date.
