In the gaseous (normal) state, radon is a colorless gas, as is true of all noble gases (see: xenon, krypton, neon, argon, helium). Due to its high radioactivity a radon light is impractical, but if one were constructed it would glow yellow-green.
In the solid state, things get very interesting with radon. As radon solidifies, it glows yellow, and then with decreasing temperature, glows an angry orange-red. This glow, or nightshine, comes from the Cerenkov light -- a product if radon's intense radioactivity. Needless to say, if you ever are viewing a glowing radon tube, you had best be standing behind very thick leaded glass.
Radon is a colorless gas and doesn't burn.
It has no color, it is said to be colorless
Radon is phosphorescent only at temperatures under the freezing point, -71 0C.
Radon is colorless.
Radon is a colorless and odorless gas.
In its gaseous state it is colorless, but when it freezes at -71°C the cooled, solid radon emits a pale yellow light. On intense cooling, it glowswith a orangish color.
Radon is a colorless gas and doesn't burn.
Radon is a gas, possible to be in buildings. Radon 222 is an isotope of radon, the most common.
Radon is a non-corrosive gas.
No. Radon is odorless.

Radon is a colorless gas and doesn't burn.
Because radon has no odor or color.
There are no elements in Radon, Radon is an element in its own right.
Radon is a gas, possible to be in buildings. Radon 222 is an isotope of radon, the most common.
Radon.
Radon is a non-corrosive gas.
Radon is NOT reactive.
No. Radon is odorless.
Although the atomic mass number of radon is often given as 220, there are 39 isotopes and isomers of radon. The common isomers of radon are : radon-219, radon-220, and radon-222.
No alchemic symbol for radon; radon was discovered around 1900.
