Radon chemisches Element

Radon is a chemical element with symbol Rn and atomic number 86. Classified as a noble gas, Radon is a gas at room temperature. H Radon is a chemical element with the symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas. It occurs naturally in minute quantities as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead and various other short-lived radioactive elements Radon is the product of the decay of other unstable, radioactive elements such as radium, thorium and actinium. The colourless, odourless, tasteless gas can be isolated from these sources but soon decays as it has no stable isotopes Radon, chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium. It is a colorless gas, 7.5 times heavier than air and more than 100 times heavier than hydrogen. Learn more about radon in this article

Ernest Rutherford is sometimes credited with the discovery of radon. He actually discovered the alpha particle radiation given off by radon. Radon became the official name for element 86 in 1923. The IUPAC chose radon from the names radon (Rn), thoron (Tn) and actinon (An). The other two names are given to isotopes of radon Chemistry of Radon (Z=86) Radon is a colorless, odorless gas, the primary source of indoor air pollution. It sinks in air because it has a high density as is therefore often found in the basements of homes, particularly in areas where with a lot of shale and boulders in the soil Radon är ett grundämne, en radioaktiv ädelgas, med beteckning Rn och atomnummer 86. Den vanligast förekommande isotopen är radon-222, som bildas vid sönderfall av radium-226 och ingår i den sönderfallskedja som börjar med uran-238 och slutar med bly-206.Radon-222, som har en halveringstid på 3,8 dagar, är en gas som sprids lätt från till exempel uran- och radiumhaltig berggrund in. 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 Rn .

Radon is a radioactive element. A radioactive element is one that gives off radiation and breaks down to form a different element. Radon is formed when heavier radioactive elements, like uranium and thorium, break down. In turn, radon breaks down to form lighter elements, such as lead and bismuth. SYMBOL

HOW WAS RADON DISCOVERED: A RADIOACTIVE ELEMENT IS DISCOVERED. In 1899 radon became the fifth radioactive element discovered after uranium, thorium, polonium, and radium. In 1900 Friedrich Ernst Dorn observed that radon gas emanated from radium. Going through several name variations, the gas became radon in 1923 The main hazard is from inhalation of the element and its solid daughters which are collected on dust in the air. Good ventilation should be provided where radium, thorium, or actinium is stored to prevent build-up of the element. Radon build-up is a health consideration in uranium mines. Recently radon build-up in homes has been a concern For use with systems running Microsoft® Windows® 7 or 10 AND equipped with AMD Radeon™ graphics, AMD Radeon Pro graphics, or AMD processors with Radeon graphics.

Radon glows orange-red when the element is cooled to its solid state Uses of Radon Gas. Radon gas is a colorless, odorless gas that most people associate with the risk of lung cancer. It does have its uses, though they are limited. Radon belongs to a group of elements called the noble or inert gases 4. These gases generally do not react with other elements to form complex molecules, which limits their usefulness. Radon or Rn is the 86th element. It was discovered in 1900 in Halle, Germany by a man named Fredrich E. Dorn. The origin of the name comes from one of its sources that creates radon, radium. Radon was one of the earliest known/ dicovered radioactive elements Radon gas is a produced during the decay of elements such as uranium and radium. The gas is comprised of radioactive particles that, when breathed in, damage the cells lining your lungs. When exposed to high levels of radon over extended periods of time, you are more likely to develop lung cancer

Radon breaks down into solid radioactive elements called radon progeny (such as polonium-218, polonium-214, and lead-214). Radon progeny can attach to dust and other particles and can be breathed into the lungs. As radon and radon progeny in the air break down, they give off radiation that can damage the DNA inside the body's cells
