The half life of 222Rn, the naturally found isotope of radon, is 3.8235 days.
The half life of radium is 1600 +/- 7 years. See related link for details.
Radon-222 is produced by the decay of radium and has a half-life of 3.8 days.
The half life of radium 226 is 1600(7) years.
Each isotope has only one half life !
The half life of 226Ra is 1 602 years.
The half life of 226Ra, the most known and stable isotope of radium is 1 602 years.
The isotope 226Rn has only a beta decay.
3.82 days and alpha decay
About 1600 years.
3.8 days.

No, Radon is an element. 222Rn belongs to the radium and uranium-238 decay chain, and has a half-life of 3.8235 days.
Radon is a gas, possible to be in buildings. Radon 222 is an isotope of radon, the most common.
Half-life time of a radioactive element is the time required for the decomposition of half of the actual mass of the element."Half life of radon is 3.8 days."This means that a particular mass of radon is reduced to half its mass in 3.8 days. The half-life period of an element does not depend upon the original mass of the element. This means that 10gms of radon will become 5gms of radon is 3.8 days, and 80gms of radon will become 40gms in 3.8 days.

Maybe, and maybe not. It depends on how large the sample is and how long "eventually" is. Though radon has a modest half-life, it still takes a long, long time for any appreciable amount to decay to the point where we can't detect it. Remember that any "sample" will contain radon atoms numbered in many powers of ten. Then there's the fact that a half-life is a statistically derived amount of time, meaning that a single given atom or a small number of atoms won't "obey" the "rule" of the half-life and decay "on schedule" per the time cited. All the atoms of radon-222 may not disappear "eventually" as was asked. But for all practical purposes, a sample might be said to disappear over geologic time. Radon-222, an isotope of the radioactive inert gas, has a half-life of 3.8235 days. That means that in 3.8235 days, half of the 222Rn sample will be gone. In another 3.8235 days, half of that remaining 222Rn will be gone. And so on. Note that the radon-222 is undergoing radioactive decay to "disappear" as was asked. Additionally, each radon-222 atom that decays will have to undergo another 7 decay events to become a stable isotope of lead. And all of this is radioactive decay.
