Radon

The Basics

The atomic number for Radon is 86, with the symbol Rn. It is a radioactive, colorless, odorless, and tasteless noble gas, also meaning that it is a nonmetal. Its atomic mass is approximately 222.0 Atomic Mass Units, and its density is 9.72 grams per liter. It occurs naturally, forming as a decay product of radium, and is the second leading cause of cancer in North America.

Fredrich Ernst Dorn and the History of Radon

Fredrich Ernst Dorn, also known as the man who discovered Radon, was a German physicist born on July 27, 1848. He discovered this radioactive substance by studying the decay process of radium in 1898. This gas was first named niton for the Latin word for "shining," but it was renamed "radon" in 1923. However, Dorn did not live to see this day, as he died on December 16, 1916.

Isotopes and What They Have to do With Radon

An isotope is an atom that has a different number of neutrons in the nucleus. Radon always has 86 protons and electrons, but a different number of neutrons, meaning that it is an isotope. The most stable isotope of Radon is 222Rn.

However, Radon can also be an ion, meaning that it will have more or less electrons. This also means that it will have a charge. More electrons means that it has a negative charge, while less electrons means that it has a positive charge. The charge of the ion depends on the amount of electrons to protons there is inside of the atom.

Half-life

The half-life of an isotope is the time taken for the radioactivity of a certain isotope to fall to half of it's original value. The half-life of the most stable isotope of Radon is 3.8 days.

Radon's energy levels

Radon has 6 energy levels, meaning that it is limited on the amount of other elements that it can bond with.

Radon's Uses

Radon is an extremely radioactive material, so it would make sense that it's the second leading cause of cancer in North America. However, Radon can also be used to treat some types of cancer. When radon is inserted into a tumor, it fights itself. This, in other words, fights fire with fire.
