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 ...
Reduction proceeds in one electron steps involving the chromium ion. Solvent effects are less important than the influence of substituents within the β-dionato moiety. Potentials range from 2.15 to 0.89 V and a linear correlation exists between E 1/2 and the sum of Hammett σ functions of the...

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...
To determine the characteristics of chromium hexacarbonyl, we can break down the problem into several steps:Step 1: Identify the Compound Chromium hexacarbonyl is denoted as Cr(CO)₆. It consists of a chromium ion coordinated
This excellent selectivity could be traceable to the ion exchange ability of the interfering ions. The crystallinity and pore size of this MOF remained unchanged in strong acidic (pH 2) and alkaline (pH 11) solutions, resulting in excellent adsorption performance over a broad pH range (3.0–9.0...
Explain why the copper element has two ion charges. Explain why the periodic trends for metal and non-metal reactivity are opposites. Why is iron more reactive than copper? Why the element having d^{10} configuration are not considered as tran...
The iron–iron distance varies according to the formal bond order required to give the iron atoms the favored 18-electron configuration. However, for the isoelectronic (C7H7)2Cr2(CO)n derivatives the CrCr distance varies little (from 2.4 to 2.5 Å) as the number of carbonyl groups is ...
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 ...
(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...
