Hassium's atomic radius is expected to be ≈126pm. Due to relativistic stabilization of the 7s orbital and destabilization of the 6d orbital, the Hs ion is predicted to have an electron configuration of [Rn]5f6d7s, giving up a 6d electron instead of a 7s electron, which is the opposite of the behaviour of its lighter homologues. The Hs ion is expected to have electron configuration [Rn]5f6d7s, analogous to that calculated for the Os ion. In chemical compounds, hassium is calculated to display bonding characteristic for a d-block element, whose bonding will be primarily executed by 6d and 6d orbitals; compared to the elements from the previous periods, 7s, 6p, 6p, and 7p orbitals should be more important.
