Roentgenium (Rg) Properties, Applications & Research

WebRoentgenium belongs to period 7 in the periodic table because it has more than 86 electrons in the valence shell. Up to period 6, there will be 86 elements that are well placed, so the remaining 25 electrons for the Rg get 7th period and 12th group along with actinide series. 4. Roentgenium block in the periodic table WebIt is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0.
