Yes. Aerogel is less dense than radon. I think it's also less dense than xenon. For a while I wondered about it too, but yes, a solid can float on a gas.
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
Radon oxide is a compound that forms when radon gas reacts with oxygen. It is a radioactive compound and can be harmful if inhaled or ingested. Radon oxide is not commonly found in nature due to radon's short half-life.
radon has no uses because it is a poisoness gas.
regular (silica) aerogel is not lighter than air but SEAgel is a form of aerogel that is lighter than air
No, pure carbon (in the form of graphite or diamond) is denser than water, so it sinks in water. However, carbon can float if it is in the form of a lightweight structure like graphene aerogel.

Yes, aerogel is a good insulator due to its low density and high porosity, which help to minimize heat transfer.
The proper spelling is aerogel. It is not specially capitalized at the beginning or in the middle, nor should it contain a hyphen or a space. The word has been in technical usage since 1931 and is not a tradename or proper noun. Common incorrect spellings include "Aerogel', "AeroGel", "aero-gel", "aero gel", and alternative phonetic spellings such as "airojell" and "aerojell".
The most common use for Aerogel is for thermal insulation. Silica Aerogel has been used to help insulate the Mars Rover and protected all the wiring from the extreme temperatures it faces in outer space.

Aerogel is 39 times more insulating than the best fiberglass ever made.
The cost of 1 kg of aerogel can vary widely depending on factors such as the type, density, and manufacturer. On average, it can range from $1,000 to $10,000.
