It is a colourless gas.
argon and xenon are the rare gas
It is a colourless dense gas.
Xenon is a colourless, odourless dense gas. It is very unreactive.
Xenon is an inert gas and it rarely and hardly reacts with other elements at standard conditions.
No two elements have the same properties.
At room temperature, xenon hexafluoride is a colourless solid. It will sublime into vivid yellow vapours.
Xenon is an inert gas; it is colorless, odorless and nontoxic. It is denser than helium, neon, and argon, but not as dense as radon.
Colorless, odorless gas. Primarily inert; reacts with Fluorine.
what are two physical properties about minerals
i think Buoyancy and Density are two physical properties that can vary even when the substance with these properties doesn't change.
Physical properties use your senses and chemical properties are when you mix two chemicals together.
Temperature and amount of the substance do not change chemical properties.
