The ground state electron configuration of ground state gaseous neutral roentgenium is [ Rn ]. 5f14. 6d10. 7s1 (a guess based upon that of gold) and the term symbol is 2S1/2 (a guess based upon guessed electronic structure). Roentgenium (111 Rg) is a synthetic element, and thus a standard atomic weight cannot be given.

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. More properties Roentgenium atoms have 111 electrons and the shell structure is 2.8.18.32.32.18.1. The ground state electron configuration of ground state gaseous neutral roentgenium is [ Rn ]. 5f14.

Flerovium was first produced by scientists working at the Joint Institute for Nuclear Research in Dubna, Russia in 1998. They bombarded atoms of plutonium with ions of calcium.This produced a single atom of flerovium-289, an isotope with a half-life of about 21 seconds.. Flerovium's most stable isotope, flerovium-289, has a half-life of about 0.97 seconds.

The first isotope to be synthesized was 272Rg in 1994, which is also the only directly synthesized isotope; all others are decay products of nihonium Roentgenium. From its position in the periodic table, in group 11 below gold, this element should have the physical properties of a noble metal and, were it long enough lived it should be possible to make compound of it although, like gold, it might be reluctant to form them. Roentgenium is an extremely radioactive chemical element with symbol Rg and atomic number 111.

Roentgenium was in fact discovered 10 years earlier on December 8, 1994, by a team of 13 nuclear physicists working at the Gesellschaft für Schwerionenforschung at Darmstadt in Germany carried out an experiment, bombarding a target of 209Bi with 64Ni ions.
