Rn Atomic Number

Posted : admin On 1/2/2022

Radon is a radioactive gas that forms naturally when uranium, thorium, or radium, which are radioactive metals break down in rocks, soil and groundwater. People can be exposed to radon primarily from breathing radon in air that comes through cracks and gaps in buildings and homes. Because radon comes naturally from the earth, people are always exposed to it.

Radon is a chemical element with atomic number 86 which means there are 86 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. Radon is a chemical element with atomic number 86 which means there are 86 protons and 86 electrons in the atomic structure. The chemical symbol for Radon is. Symbol: Rn Atomic Number: 86 Atomic Mass: 222 Number of Protons/Electrons: 86 Number of Neutrons: 136 Classification: Noble Gases Discovery: 1898 Discoverer: Fredrich Ernst Dorn Uses: treatment of cancer. Distribution in ocean Radon is present in seawater as the radioactive isotope 222 Rn (half-life of only 3.82 days), which is produced by decay of 226 Ra. 222 Rn is in secular equiilibrium with its parent isotope except near the sediments and at the seasurface. An excess of 222 Rn, relative to the activity of 226 Ra, may occur near the sediment-water interface as radon gas diffuses from.
