It is Xenon when it has been cooled to below 161.4 K.
xenon is stable compound.......
At room temperature, xenon hexafluoride is a colourless solid. It will sublime into vivid yellow vapours.
Under standard conditions, it is a gas.

All the noble gases have solid forms that are denser than their liquid forms, so no, the liquid form is not denser than the solid form of Xe.
At room temperature, xenon hexafluoride is a colourless solid. It will sublime into vivid yellow vapours.
"At room temperature" xenon is a gas. However, at other temperatures, its 'natural state' will be liquid or solid.
Under high pressure - around 150 gigaPascals - xenon turns metallic. In this phase it has a blue colour.
At normal temperature and pressure it is a gas.
At normal temperature and pressure it is a gas.
