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]

The proposed name paid homage to the acclaimed British chemist Sir Humphry Davy, who himself had discovered a multitude of elements, including sodium, potassium, calcium, and magnesium.
