The trivalent chromium ion has been successfully used as the optical activator in a large number of tunable crystalline laser materials. Some of the unique properties of its 3d 3 electron configuration which have led to this widespread success are reviewed. It is found that a combination of ...
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 ...
For a d 3 configuration ion, the 120×120 complete energy matrix which contains the electron–electron repulsion interaction, the ligand field interaction... AJ Mao,XY Kuang,H Wang,... - 《Journal of Alloys & Compounds》 被引量: 16发表: 2008年 Synthetic and structural studies on Group 13...

When ion-exchange capacity and reversibility of pure PPy and CNT/PPy nanocomposite thin films were compared using electrochemical quartz microbalance (EQCM) in NaCl, NaClO4, NaNO3, Na2SO4, and NaHCO3 electrolyte solution, the results indicated that the ion exchange kinetics of PPy improved by ...
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 ...
How many unpaired electrons are in the predicted ground state electron configuration of a neutral ruthenium (Ru) atom according to the Aufbau principle? How many unpaired electrons are in the electron structure of _{24}Cr? For a V^{3+} ion in its ground electronic state: a....
The product of the oligomerization has been characterized by the positive-ion mode MALDI-TOF mass spectrometry throughout selecting a matrix that facilitates its ionization (DHB). The MALDI-TOF was used to the direct molecular weight determination of the oligomeric poly(2-chloroallyl alcohol). More...
The nano-antenna patterns were milled by FEI Helios NanoLab 600 dual beam focused ion beam (FIB) system. All the scanning electron microscope (SEM) images were taken using either FIB or Electron Beam Lithography (EBL-Raith 150) system. For the characterization of our devices, a Lastek Q-...
ion has a similar radius (63 pm) to Al3+ (radius 50 pm), and they can replace each other in some compounds, such as in chrome alum and alum. Chromium(III) tends to form octahedral complexes. Commercially available chromium(III) chloride hydrate is the dark green complex [CrCl2(H2O)4...
