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 ...
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...

For chromate removal, arc-assisted carbon (AC), activated carbon (RC), and carbon aerogel have been used for ion exchange electrode [8,9]. Hexavalent chromium, [Cr(VI)] may exist in the aqueous phase in different anionic forms, such as Cr2O72−, CrO42−, or HCrO4−, with tot...
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-...
The number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electron configuration is [Ar] 3d5 4s1. Louis Nicolas Vauquelin first discovered chromium in 1797 and first isolated it the following year. The chromium atom has a radius of 128 pm and a Van der Waals ...
