Electron configuration of Radon

Electron Configuration Of Radon The Electron configuration of Radon is Xe 4f14 5d10 6s2 6p6. Radon is a chemical element which is represented by the symbol Rn and whose atomic number corresponds to 86. There are a total of 37 isotopes of it, which are known from 195Rn to 231R. It is the heaviest of those which make up the gases nobles, and each of its isotopes has a short half-life. The most durable is 222Rn.

It is obtained by the natural radioactive decay of uranium, which is found organically in rocks and soils.

In addition, it is found in water. It emanates easily from the ground then passes into the air, followed by its disintegration and the emission of radioactive particles. The Electron configuration of radon is Xe 4f14 5d10 6s2 6p6. Its spectrum of elements is very similar to that of inert gases.

Electron configuration of Radon

Electron Configuration Of Radon The Electron configuration of radon is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 4f14 5d10 6s2 6p6 Adding all these indices together, the total is 86, which is the total number of electrons that radon has, which is equal to its atomic number.

According to their Electron configuration, these are distributed as follows:

  • 2 electrons orbiting 1s
  • 2 electrons in 2s orbit
  • 6 electrons in 2p orbit
  • 2 electrons in 3s orbit
  • 6 electrons in orbit l 3p
  • 10 electrons in 3d orbit
  • 2 electrons in 4s orbit
  • 6 electrons in 4p orbit
  • 10 electrons in 4d orbit
  • 2 electrons orbiting 5s
  • 6 electrons in 5p orbit
  • 14 electrons orbiting 4f
  • 10 electrons in 5d orbit
  • 2 electrons in 6s orbit
  • 6 electrons in 6p orbit

radon isotopes

All 37 isotopes of this element are radioactive. Its most stable isotope is 222Rn, whose half-life is 3.823 days, the decomposition of which gives way to 218Po. Among its other isotopes are 217Rn, 218Rn, 219Rn, 220Rn and 222Rn, which are produced after the decay of 217At, 218At, 223Ra, 224Ra and 226Ra, in the same order. There are also the 235U, 232Th, 237Np and 238U

Radon Effects on Health

In nature, this element is mostly in the gas phase, so humans are exposed to radon by breathing air.

In outdoor air, their background levels are usually very low, however, in enclosed areas this changes, they reach very high levels. In buildings, homes and schools, which are enclosed spaces, radon enters through cracks in underground built-up areas, such as basements.

Exposure of a person to high levels of this element through breathing can cause lung disease. If the exposure is long-term, ie over several years, lung cancer may develop. Radon can also be present in many deep wells from which humans are supplied with drinking water, so there is exposure through this route as well.

In groundwater, radon levels are very high, but radon is regularly released into the air when groundwater reaches surface water.

It is important to know that although radon can be radioactive, it emits very little gamma radiation, so exposure to this element is unlikely to cause harmful effects without very close contact with its components.

To date, other than the lungs, it is not known whether radon is capable of causing health effects in other organs, and the effects that radon in food and drinking water can cause are also unknown. .

Environmental effects of radon

Most of them composed of this element found in nature come from human activities. Radon reaches the environment through phosphate and uranium mines, through soil and also through coal combustion.

Part of this element present in the soil rises to the surface and enters the air by evaporation. Although it reaches surface waters, most of it will remain in the ground.

Half of the amount of radon decays into other components. Its radioactive half-life is about four days in total, which means compounds of this element will cause less damage every four days.
