$\begingroup$ That melting point trend seems pretty close to linear, aside for Oganesson. Is that coincidence, or is there something about Oganesson which makes it buck a trend? (e.g. like relativistic effects changing Au/Hg properties.) $\endgroup$

$\begingroup$ As an article states, relativistic effects shifts melting temperature up by about $100K$, but we should not forget that for $\text{Og}$ this is just an estimation (modelling) of a melting property, while for the other noble gases- these melting points are more or less confirmed experimentally (measured). So we can't actually align linear trend to Oganesson simply due to the fact that we be comparing apples to the oranges. $\endgroup$

$\begingroup$ This made me wonder whether anyone has ever produced a sample of liquid radon. Apparently just once, in 1909. $\endgroup$
