the half-life of radon-222 is 3.8 days. How much of a 100g sample is left after 15.2 days?

Because radon is a gas, it will tend to seek a gaseous phase. Natural radon Radon-222 is the most stable isotope of radon, with a half-life of approximately 3.8 days. It is transient in the decay chain of primordial uranium-238 and is the Radon-222 (. 222.

Radon is a colorless, odorless gas, a radioactive byproduct of radium. It is part of the natural radioactive decay series starting with uranium-238. It is radioactive with a half-life of 3.8 days, decaying by the emission of alpha particles to polonium, bismuth, and lead in successive steps.
