The electronic ground states of complexes containing a paramagnetic transition metal ion with d n electron configuration and a bound phenoxyl radical ( S=1/2) are attained via an intramolecular anti- or ferromagnetic exchange coupling mechanism the nature of which depends on the actual d n ...
Electron configuration: [Ar]3d54s1Oxidation state: 6,4,3,2Crystal structure: cubic Chromium is a malleable hard metal best known for its attractive luster when polished. Chromium gets its name from the Greek word for color due to the many colorful compounds that can be made from ...

The oxidation state +3 is the most stable, and a large number of chromium(III) compounds are known. Chromium(III) can be obtained by dissolving elemental chromium in acids like hydrochloric acid or sulfuric acid. The Cr3+ ion has a similar radius (63 pm) to the Al3+ ion (radius 50 p...
Two layered MOFs (FIR-53 [155] and Ag-3 [157]) have been reported for Cr2O72− adsorption through ion exchange. A typical example of a layered MOF ion exchanger is Ag-3 synthesized by reacting AgBF4 and 4-(5-methyl-3-pyridine)-1,2,4-triazole in CH3CN at room temperature. The...
Step 3: Write the Electron Configuration of ChromiumThe electron configuration of chromium (Cr) in its elemental form is (Ar) 4s² 3d⁴. Since chromium is in the zero oxidation state, it retains all its electrons. Hint: Use the periodic table to find the electron configuration of chromium...
What is the noble gas electron configuration of the chromium ion, Cr+6? Is the ion paramagnetic or diamagnetic? What is the set of quantum numbers that represents its last electron?This is pretty much fantasy. Chromium does not form a +6 ion in a compound. It might be possible to hit ...
The CFT for the d3 ion CrIII (electron configuration [Ar] 3d3) will be discussed in the following. As the result of the threefold ionization of metallic chromium (cf. Table 1) three electrons from the orbital with the highest principle quantum number had been removed. As a simplification,...
(III) is in the electron configuration 3d3of the valence electrons and is, in aqueous solutions, almost exclusively known as an octahedrally coordinated ion. In said configuration, the ion shows a high ligand field stabilization energy (LFSE). This results in markedly low reaction velocities at...
