Radon is a chemical element; it has symbol Rn and atomic number 86. It is a radioactive noble gas and is colorless and odorless. Of the three naturally occurring radon isotopes, only 222 Rn has a sufficiently long half-life (3.825 days) for it to be released from the soil and rock where it is generated.
1 sty 1990 · The radon atom possesses a stable closed shell electronic configuration which gives it the chemical properties of a noblegas element. It behaves as expected by comparison with the other inert gases in the periodic table including helium, neon, argon, krypton, and xenon.
12 sie 2016 · Atomic, physical and chemical properties of radon including density, melting point, heat of fusion, heat of vaporization, oxidation states, electronegativity and first ionization potential (energy needed to remove the outermost (highest energy) electron from a neutral atom in the gaseous state) are given in Table 1.2.
It is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0. The sum of the oxidation states within a compound or ion must equal the overall charge.
27 wrz 2024 · Radon atoms possess a particularly stable electronic configuration of eight electrons in the outer shell, which accounts for the characteristic chemical inactivity of the element. Radon, however, is not chemically inert.
26 cze 2024 · Compounds: Though rare, radon can form compounds with highly electronegative elements, such as fluorine. Examples include radon difluoride (RnF2). These compounds are generally unstable and of significant interest in research. Isotopes: Radon has several isotopes, with Radon-222 being the most stable and common.
1 mar 2019 · Properties: Radon has a melting point of -71°C, boiling point of -61.8 °C, gas density of 9.73 g/l, specific gravity of the liquid state of 4.4 at -62°C, specific gravity of the solid state of 4, usually with a valence of 0 (it does form some compounds, however, such as radon fluoride). Radon is a colorless gas at normal temperatures.
