The radon isotopes 222Rn and 220Rn are natural isotopes.
Radon is a chemical element and does not have neurons or any other biological components. It is a naturally occurring radioactive gas that is colorless, odorless, and tasteless.
It is radon that we see formed from the decay of naturally radioactive substances in the earth's crust.
Radon is a naturally occurring radioactive gas that is produced from the decay of uranium in soil and rocks. It is found in the Earth's crust and can seep into buildings through cracks and openings in the foundation. This is why radon is still present in nature.
Radon is the name of the heaviest noble gas.
Thallium is a naturally occurring element in the Earth's crust. It is not a man-made element.
Radon is a gas at room temperature, and quite a bit below it, too. A link can be found below.
The gas is Radon.
No, radon is a colorless, odorless, and tasteless gas that is a naturally occurring radioactive element. It is not flexible in the physical sense like a material that can bend or be molded. Radon is known to be harmful to human health when present in high concentrations.
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
Radon
Radon is one of the noble (inert gases), is radioactive (half-life of about 4 days, decaying to polonium), and is naturally occurring in relatively small quantities. Whether or not it is the heaviest of this group, I am not sure...perhaps someone else can verify.
radon is a noble gas, so it does not form compounds.
