26 cze 2024 · Compounds: Though rare, radon can form compounds with highly electronegative elements, such as fluorine. Examples include radon difluoride (RnF2). These compounds are generally unstable and of significant interest in research. Isotopes: Radon has several isotopes, with Radon-222 being the most stable and common.
Radon comes from other radioactive elements. More recently, it was observed that this radioactive gas is present in very small amounts in soils and minerals. Its accumulation in well-insulated, tightly sealed buildings, however, constitutes a health hazard, primarily lung cancer.
Radon is a chemical element; it has symbol Rn and atomic number 86. It is a radioactive noble gas and is colorless and odorless. Of the three naturally occurring radon isotopes, only 222 Rn has a sufficiently long half-life (3.825 days) for it to be released from the soil and rock where it is generated.
After Neil Bartlett's discovery in 1962 that xenon can form chemical compounds, a large number of xenon compounds have been discovered and described. Almost all known xenon compounds contain the electronegative atoms fluorine or oxygen.
1 sty 1984 · Major areas of environmental research include the identification of geological factors associated with high radon levels, the behavior of radon daughters in various aerosol distributions, and the effects of certain architectural factors on radon daughter equilibrium status.
27 wrz 2024 · Radon, chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium. It is a colorless gas, 7.5 times heavier than air and more than 100 times heavier than hydrogen. Learn more about radon in this article.
