Other than nuclear properties, no properties of roentgenium or its compounds have been measured; this is due to its extremely limited and expensive production and the fact that roentgenium (and its parents) decays very quickly. Properties of roentgenium metal remain unknown and only predictions are available. Chemical Roentgenium itself, however, has no commercial applications and much remains unknown about its properties due to its extremely short half-life. 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. More properties Roentgenium atoms have 111 electrons and the shell structure is 2.8.18.32.32.18.1.

Roentgenium is a chemical element with the symbol Rg and atomic number 111. In the periodic table, it is a d-block transactinide element. It is a member of the 7th period and is placed in the group 11 elements, although no chemical experiments have been carried out to confirm that it behaves as the heavier homologue to gold in group 11 as the ninth Muons in roentgenium (Rg) Z A [g/mol] ρ [g/cm3] I [eV] a k = m s x0 x1 C δ0 111 (Rg) [282.167(5)] ??

The nucleus is composed of protons and neutrons. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. 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.The first isotope to be synthesized was 272 Rg in 1994, which is also the only directly synthesized isotope; all others are decay products of nihonium, moscovium, and tennessine, and possibly copernicium, flerovium, and livermorium. uence properties of atoms Nuclear processes also have many practical applications: Uses of radioactivity in research, health and industry, e.g.
