Editing Seaborgium (section)

===Physical===
Seaborgium is expected to be a solid under normal conditions and assume a [[body-centered cubic]] crystal structure, similar to its lighter [[congener (chemistry)|congener]] tungsten.<ref name="bcc" /> Early predictions estimated that it should be a very heavy metal with density around 35.0&nbsp;g/cm<sup>3</sup>,<ref name="Haire" /> but calculations in 2011 and 2013 predicted a somewhat lower value of 23–24&nbsp;g/cm<sup>3</sup>.<ref name="density" /><ref name="kratz" />
