      Radon, with an atomic number of 86 and symbol Rn, was the fifth radioactive element to be discovered, and it is the heaviest naturally occurring radioactive member of the noble gases. The noble gases, which belong to Group 18 in the periodic table, include helium, neon, argon, krypton, xenon, radon, and ununoctium. Radon is a colorless, odorless, tasteless, and chemically inert gas. After the uranium present in rock, soil, and water undergoes radioactive decay, the radon that is formed then travels through the soil to the air above. Studies have shown that radon can cause lung cancer.
