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.
What else can I help you with?
What is the appearance of color of radon?
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.
What color would radon burn?
Radon is a colorless gas and doesn't burn.
Can you smell radon?
No. Radon is odorless.
What is the chemical symbol for radon?
The chemical symbol of radon is Rn.
What equipment would I need for radon testing?
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

Explain why radon's potential health hazard has been discovered only recently even though this gas has always been emitted from uranium-containing rocks in the ground?
Because radon has no odor or color.
What are the elements in Radon?
There are no elements in Radon, Radon is an element in its own right.
What color would radon burn?
Radon is a colorless gas and doesn't burn.
What is the reactiveness of radon?
Radon is NOT reactive.
Can you smell radon?
No. Radon is odorless.
What is radon's odor?
Radon is odorless and poisonous.
What is the ductile of radon?
Radon is a gas, no ductility.
What is radon's hardness?
Radon is a gas, no hardness.
What is the chemical symbol for radon?
The chemical symbol of radon is Rn.
Does radon help fight against cancer?
No, not radon. Radon is known to cause lung cancer.
