Davyum

Davyum was the proposed name for a chemical element found by the chemist Serge Kern in 1877.[1][2][3] It was shown that the material was a mixture of iridium and rhodium.[4] In the 1950 it was proposed that the new metal might have contained also rhenium, which was not discovered at the time of Kern.[5]
