Radon

==Radon is number 86 on the periodic table. Its initial is Rn. It has an atomic number of 86, and an atomic mass of 222.0 amu. The number of protons and electrons are 86. Electrons are part of the atom that has a negative charge electrical charge. A proton is part of the atom that has a positive charge. This means that Radon has 86 positive and 86 negative electrical charges. It has 136 neutrons. Neutrons is part of an atom that does not have a positive or negative electrical charge, that means that neutrons are neutral.==

==The scientist Fredrich Ernst Dorn discovered Radon in 1900. The name of origin comes from radium. Radon is obtained from the decay of radium. Radon was probably first used by people bathing in hot springs, since Radon is present in many hot springs. Before it was called Radon, the scientists William Ramsay and Robert Whytlaw-Gray named it 'Niton'. It has been called Radon since 1923. == ==Radon’s crystal structure is cubic. It has no color, taste or smell. This noble gas does not react with other elements, and it does not form compounds.Radon is classified as a radioactive noble gas. It is the heaviest noble gas in the periodic table.==

==Radon can be very dangerous as well as helpful. Many times Radon is used to kill cancer cells. Even though it kills the cancer cells, it can also cause them. Radon can cause lung cancer. Radon is sometimes used to make radioactive weapons. Since many times Radon can occur in granite, there is a concern that it may build up inside houses and pose a risk of cancer. Grand Central Station in New York is famously radioactive for this reason. Radon gives off alpha rays, and there is a detectable amount in the atmosphere. Radon is the secon leading cause for lung cancer in the United States today. ==
 * You can also use Radon in scientific areas. For example many times they use it to predict earthquakes. Many people think that if you take a sauna bath in Radon water can help arthritis.
