What Is Radon Atomic Number
Radon is one of the noble gases known for their extremely low reactivity. Thus, it can be found in our planet in its pure form. It is odorless and has no color, but is highly radioactive. It was discovered in the very beginning of the 20th century and given the name after the word radiation. It is considered that radon has no importance for biological life on our planet, but as the evidence has shown it can play a role in evolution and genetic modifications, in particular. Generally, radon is used in nuclear chemistry and for treatment of certain types of cancers.
