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.
After the published tables the silica aerogel is a very good thermal insulator.
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.
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.
regular (silica) aerogel is not lighter than air but SEAgel is a form of aerogel that is lighter than air
NO
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.

the aerogel
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".

Aerogel is 39 times more insulating than the best fiberglass ever made.
After the published tables the silica aerogel is a very good thermal insulator.
There are no elements in Radon, Radon is an element in its own right.
