Radon electron configuration

What do the electron configurations of neon, argon, krypton, xenon, and radon have in common ... 

Es, [Rn]ls 5f, core electron configuration corresponds to the noble gas radon. Besides that there are 2 electrons in the 75-orbital and 11 electrons in the 5/-orbitals. 

Extend the aufbau sequence through an element that has not yet been identified, but whose atoms would completely fill 7p orbitals. How many electrons such an atom would have Write its electron configuration using noble-gas notation for the previous noble gas, radon. 

Rare gases are those elements in Group VIIIA of the periodic table helium, neon, argon, krypton, xenon, and radon. They are not necessarily rare, however, and are also called the inert or noble gases. Due to their electron configurations, helium, neon, and argon are extremely nonreactive, while others undergo some reactions. 

As another example, at the beginning of 1962 the elements helium through radon were commonly dubbed inert gases, believed to form no chemically bound compounds because of the stability of their electron configurations. Later that same year, Bartlett... 

The regular filling of the 6p orbitals accounts for the outer electronic configurations of the elements from thallium to radon, thus completing the third long period with its integral f-block elements. 

Suggested electron configurations (beyond radon and xenon) for gaseous atoms of actinide and lanthanide elements. 

Suppose that scientists were to discover a new element, one that has the chemical properties of the noble gases, and positioned directly below radon on the periodic table. Assuming that the g orbitals of the elements preceding it in the period had not yet begun to fill, what would be the atomic number and ground state electron configuration of this new element ... 

Radon, Rn At. no. 86, at. wt 222, mp—71°C, bp -61.8°C. Radon is an intermediate radioactive decay product of Ra. Rn, the most stable isotope of radon, is obtained as a gas from aqueous solutions of RaCl2 and has been used as a radiation source and as a gaseous tracer. It is a considerable hazard in uranium mines. In some areas, radon in basements and in ground water is a potential health hazard because of its radioactivity. The ground state electronic configuration of radon is [Xe]4f " 5d °6s 6p. Because radon is intensely radioactive, the chemistry of radon has only been investigated on the tracer scale. Radon forms compounds, particularly a fluoride (likely RnF2), and solid adducts between the fluoride and Lewis acid fluorides. 

In our discussions of bonding, we pointed out the relative stability of the electron configurations of the Group VIIIA noble gases. For many years, it was thought that because the atoms of these elements had completed octets, Ihe noble gases would be completely unreactive. Consequently, these elements were known as inert gases. Compounds of krypton, xenon, and radon have since been prepared, however, so (he term is not quite appropriate.

Actinide atoms, in their ground configuration, comprise the closed shell electronic structure of the noble gas radon... 

Very recent sophisticated CASSCF/CASPT2 calculations (61) shed some light on this problem. Radon et al. (61) performed an analysis of the number of configurations and calculated the weight of the given resonance structures. Consequently, FeP-NO can best be characterized as mixture of Fe(II)-NO0 and Fe(III)-NO resonance structures. The Fe(I)-NO+ electronic structure participates only with a few %.
