뢴트게늄 개요

Should roentgenium prove chemically similar to gold, as calculations suggest, it would be a noble metal at the foot of group 11. The element sits in period 7 with the configuration [Rn] 5f14 6d9 7s2, atomic number 111 and a relative atomic mass of 282.0, and is named for Wilhelm Rontgen, who discovered X-rays. Its electronegativity is undetermined and its properties are formally classed as unknown, since no chemical experiment has yet been performed on it. Relativistic contraction of the innermost orbitals is expected to be pronounced at this atomic number, and predictions of the element's behaviour depend heavily on how that contraction is modelled.
