Periodic Table -> Radon RadonRadon DetailsRadon Symbol: RnRadon Atomic Number: 86Radon Atomic Weight: (222)What is Radon?Radon (atomic number 86, symbol Rn) is a gas and chemical element that is harmful for human health. In the U.S. alone, it is the main cause for over 20 thousand ...
Radon is a chemical element; it has symbol Rn and atomic number 86. It is a radioactive, colourless, odourless, 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 various short-...
radon- a radioactive gaseous element formed by the disintegration of radium; the heaviest of the inert gasses; occurs naturally (especially in areas over granite) and is considered a hazard to health atomic number 86,Rn chemical element,element- any of the more than 100 known substances (of ...
and a radioactive chemical element with an atomic number of 86 (in the periodic table) and an atomic weight of 222. It is one of the products of spontaneous uranium decomposition (238U), and directly issues from radium alpha decay (the name radon is from radium,226Ra). Uranium is a nat...
The chemical behaviour of radon is similar to that of a metal fluoride and is consistent with its position in the periodic table as a metalloid element. Element Properties atomic number 86 stablest isotope (222) melting point −71 °C (−96 °F) boiling point −62 °C (−80 °F...
The abscissa is neutron number (N) and the ordinate is proton number (Z). The box corresponding to any pair (Z, N) represents an isotope; an element is represented by a horizontal row. Boxes for stable isotopes are shown with solid outline; for the noble gases, approximate solar (in ...
[9] However, due to periodic trends, radon has a lower electronegativity than the element one period before it, xenon, and is therefore more reactive. Radon is sparingly soluble in water, but more soluble than lighter noble gases. Radon is appreciably more soluble in organic liquids than in ...

Radon is a noble gas on the far right side of theperiodic table of the elements. I’m sure you know them by heart: helium, neon, argon, krypton, xenon, radon, and now, apparently, a new one named oganesson. But it’s not radon’s association with the formerly-called inert elements...
How many neutrons are there in an atom of lead whose mass number is 208? What is nobelium's atomic mass? What is the mass number of the isotope lithium-7? What is the mass number of molybdenum? Where is radon on the periodic table?
