In excellent agreement, these approaches show Og to be a solid at ambient conditions with a melting point of ~325 K. In contrast, calculations in the nonrelativistic limit reveal a melting point for Og of 220 K, suggesting a gaseous state as expected for a typical noble gas element. ...

: A covalent bond is formed by sharing of electrons (equally or partially polarized) between the two non-metals. Octet rule: By obtaining eight electrons around the valence shell of an element, then compound satisfied the octet rule and thus, achieved the ...
Noble Element Simulation Technique is used to simulate noble-element energy deposition microphysics. - NESTCollaboration/nest
Depending on temperature and some other factors, matter can exist in several states. The three most common states are known assolid,liquidandgas. A single element or compound of matter might exist in more than one state, depending on the temperature and pressure conditions. One common example ...
So, moving up to the next heaviest noble gas, you getradon. Radon does exist in nature and is an extremely dense gas. Radon has a density of around 4.4 grams per cubic centimeter. Most sources consider this element to be the heaviest noble gas. ...
