6d10. 7s1 (a guess based upon that of gold) and the term symbol is 2S1/2 (a guess based upon guessed electronic structure). Roentgenium 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 272Rg 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.

None are stable. The most stable isotope is 281 Rg, with a half-life of 23 seconds. Roentgenium is predicted to be a very heavy noble metal, solid under normal conditions and to crystallize in the body-centered cubic structure, unlike its lighter congeners which crystallize in the face-centered cubic structure, due to its being expected to have different electron charge densities from them.
