This small radius and high weight cause it to be expected to have an extremely high density of around 46 g·cm −3, over twice that of osmium, currently the most dense element known, at 22.61 g·cm −3; element 164 should be the second most dense element in the first 172 elements in the periodic table, with only its neighbor unhextrium ...
Unbihexium is predicted to be a chemically active superactinide, exhibiting a variety of oxidation states from +1 to +8, and possibly being a heavier congener of plutonium. An overlap in energy levels of the 5g, 6f, 7d, and 8p orbitals is also expected, which complicates predictions of chemical properties for this element.
A g-block, with azimuthal quantum number 4, is predicted to begin in the vicinity of element 121. Though g-orbitals are not expected to start filling in the ground state until around element 124 – 126 (see extended periodic table ), they are likely already low enough in energy to start participating chemically in element 121, [ 10 ] similar ...
