Pu vii
WebThe addition in Pu(VII) solution of the aliquot of Pu(VI) solution reduces the absorbance of the solution at any wave length in proportion to dilution. Consequently there is no the influence of Pu(VI) on the absorption spectrum of Pu(VII). Thus, it is become obvious no Pu(VIII) formed in the course of ozonolysis of Pu(VII) alkaline solution. ...

Plutonium compounds are compounds containing the element plutonium (Pu). At room temperature, pure plutonium is silvery in color but gains a tarnish when oxidized. The element displays four common ionic oxidation states in aqueous solution and one rare one: • Pu(III), as Pu (blue lavender) WebSep 15, 2016 · A central goal of chemistry is to achieve ultimate oxidation states, including in gas-phase complexes with no condensed phase perturbations. In the case of the actinide elements, the highest established oxidation states are labile Pu(VII) and somewhat more stable Np(VII). We have synthesized and characterized gas-phase AnO3(NO3)2– …
WebThe highest known actinide oxidation states are Np(VII) and Pu(VII), both of which have been identified in solution and solid compounds. Recently a molecular Np(VII) complex, … WebFeb 1, 2010 · In a wide range of alkali concentrations, from 1 to 15 M, the Pu(VI) ozonation yields a mixture of Pu(VII) and Pu(VIII). It was proved that Pu(VII) exists in aqueous alkali solutions in the form ...
WebApr 1, 2007 · A new Pu(VII) compound, Na3[PuO4(OH)2]·2H2O, was prepared by X-ray diffraction analysis, and its structure was studied. To reveal the character of actinide contraction in going from Np(VII) to Pu ... WebPlutonium is a reactive metal. In moist air or moist argon, the metal oxidizes rapidly, producing a mixture of oxides and hydrides. If the metal is exposed long enough to a limited amount of water vapor, a powdery surface coating of PuO 2 is formed. Also formed is plutonium hydride but an excess of water vapor forms only PuO 2.. Plutonium shows …
WebApr 14, 2024 · Gibson et al. recently showed that upon reducing Pu V O 4, Pu is oxidized to form the Pu VII O 4 − ion. 23 Zaitsevskii and co-workers performed relativistic DFT calculations on AnO 4 (An = Pu, Am, and Cm) molecules and found that the ground states have dioxide-superoxide-like structures [AnO 2](O 2) with all three actinoids in OS = V. …
WebThe redox potential of the pair Pu(VII)/Pu(VI) in 1 M KOH is in the range of 0·76-1·24 V. Absorption spectra of alkaline solutions of Np(VII) and Pu(VII) are independent of the way they were taken and are practically unaffected by changing concentration of OH − ions over a broad range. The colour of solutions of Pu(VII) and Np(VII) in the ... microtech merlot ultratech review244 Pu has the longest half-life of all transuranic nuclides and is produced only in the r-process in supernovae and colliding neutron stars; when nuclei are ejected from these events at high speed to reach Earth, 244 Pu alone among transuranic nuclides has a long enough half-life to survive the journey, and … See more Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94.
