Davyum

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