What is roentgenium (Rg)?
What is roentgenium (Rg)?
Roentgenium(Rg) is a radioactive element created artificially (extremely radioactive synthetic element) and not found in nature. The element was discovered by Peter Armbruster and Gottfried Münzenberg in the year 1994. It is a D-block transactinide element in the periodic table.
What is the atomic weight of roentgenium?
Roentgenium (111 Rg) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no stable isotopes.
What is the electrode potential of roentgenium?
Roentgenium is predicted to be a noble metal. The standard electrode potential of 1.9 V for the Rg 3+ /Rg couple is greater than that of 1.5 V for the Au 3+ /Au couple.
When was roentgenium first synthesized?
Roentgenium was first synthesized by an international team led by Sigurd Hofmann at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany, on December 8, 1994.
