Radon information, including Technical Data, Safety Data and its high purity properties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included.
 Radon is a Block P, Group 18, Period 6 element. The number of electrons in each of Radon's shells is 2, 8, 18, 32, 18, 8 and its electronic configuration is [Xe] 4f14 5d106s26p6. In its elemental form radon's CAS number is 10043-92-2. The radon atom has a radius of 240.pm and it's Van der Waals radius is 200.pm. Radon is highly radioactive and a carcinogen.
Radon was discovered by Friedrich Ernst Dorn (Germany) in 1900.
The origin of Radon is derived from the name of the element radium. At first Radon was called Niton, from the Latin word ‘Nitens’ which means shining.

Radon Safety Data. The safety data for radon metal, nanoparticles and its compounds can vary widely depending on the form. For potential hazard information, toxicity, and road, sea and air transportation limitations, such as DOT Hazard Class, DOT Number, EU Number, NFPA Health rating and RTECS Class, please see the specific material or compound referenced in the left margin. Radon compounds have no biological role.
Ionization Energy. The ionization energy for radon (the least required energy to release a single electron from the atom in it's ground state in the gas phase) is stated in the following table:
| 1st Ionization Energy |
1037.08 kJ mol-1 |
| 2nd Ionization Energy |
- kJ mol-1 |
