There are currently 118 known elements listed on the periodic table; from hydrogen, which has a single proton in its nucleus, ...

culminating in element 118, oganesson. However, creating these elements is no small feat. Production rates plummet as atomic numbers rise, with only one atom of oganesson produced per month.

A pathway that should allow the production of new nuclei beyond oganesson-294 (Z=118), the heaviest nucleus ever studied by nuclear physicists. The next step is to synthesize element 120. Although ...

Oganesson, Og, was discovered in 2002. It is placed below radon in group 0. Assuming that it is a gas at room temperature, predict its density and explain your answer.
