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.
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.
No. Radon is odorless.
The chemical symbol of radon is Rn.
You need a radon detector to perform radon testing. Essentially it's a geiger counter. Radon is radioactive and you locate it just the same way. Many radon alarms are available for areas where Radon is a problem. You would need a radon detector for radon testing. You can purchase one from amazon.com for $130 shipped. http://www.amazon.com/dp/B000CEAY64

Because radon has no odor or color.
Radon is a colorless gas and doesn't burn.
There are no elements in Radon, Radon is an element in its own right.
Radon is NOT reactive.
No. Radon is odorless.
Radon is odorless and poisonous.
Radon is a gas, no ductility.
Radon is a gas, no hardness.
The chemical symbol of radon is Rn.
No, not radon. Radon is known to cause lung cancer.
