One of the Noble gases..

Element/ Density (g/dm3)

Helium 0.1786
Neon0.9002
Argon 1.7818
Krypton 3.708
Xenon 5.851
Radon 9.97

The first two Helium and Neon are lighter than air; which leaves Argon, Krypton, Xenon and Radon.

krypton
Krypton is considered to be a non-toxic asphyxiant.[37]Krypton has a narcotic potency seven times greater than air, so breathing a gas containing 50% krypton and 50% air would cause narcosis similar to breathing air at four times atmospheric pressure. This would be comparable to Scuba diving at a depth of 30 m (100 ft) (see nitrogen narcosis) and potentially could affect anyone breathing it. Nevertheless, that mixture would contain only 10% oxygen and hypoxia would be a greater concern.

This riddle is referring to Radon-222, a dense noble gas that is a byproduct of uranium-238 decay and is radioactive. Radon is colorless, odorless, and tasteless, making it hard to detect without proper testing. It can seep into homes through cracks and openings in the foundation, so it is important to regularly test for radon and take necessary precautions to prevent exposure.
