What does roentgenium look like?
No one knows for sure what roentgenium looks like, but it has been placed under copper, silver and gold in the Periodic Table. Theoretical chemists have had fun predicting its properties, and they think that if anyone ever sees any roentgenium metal, it is likely to be silver in colour and it will be very unreactive.
What is roentgenium used for?
Uses of Roentgenium: The only uses of roentgenium are for scientific study, to learn more about its properties, and for the production of heavier elements. Roentgenium Sources: Like most heavy, radioactive elements, roentgenium may be produced by fusing two atomic nuclei or via decay of an even heavier element.
What type of element is Dubnium?
