Surface Forms

roentgenium singular
roentgeniums plural

Morphology

roentgenium = roentgen (semi-transparent) = roentgen + ium

The element name is formed by adding the standard chemical suffix '-ium' to the name 'roentgen', which signals an element but requires knowledge of the eponym.

Etymology

Roentgenium is named after the scientist Roentgen, who discovered 'X-rays', so the name links the element to radiation and helps explain why it is a radioactive heavy element with the symbol Rg.
