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 ...
What is the formula of the phosphate ion? What is the charge on the ion that Selenium forms in an ionic compound? What is the name of the anion CO32-? Which ion should be hardest to form? Mg^{3+} or Al^{3+}. What is the correct na...
The Cr (III) was studied as a metal center because Cr(III) has d3 electronic configuration and adopted an octahedral geometry. The chromium(III) porphyrin is considered to be the five-coordinate CrIII(TPP)(Cl) complex, which coordinates a sixth ligand L forming stable six-coordinate ...
Give the symbol of an atomic ion of the following electron configuration: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6. What is the atomic number of the element located in group 16, period 2 of the periodic table? An atomic cation with a charge of +1 has the following electron configuration:...
-3 less common -4 less common Pauling Electronegativity oxidation state: 2 1.66 Electron Configuration Orbital Occupancy [Ar] 3d5 4s1 [Ar] represents the closed-shell electron configuration of argon Orbital Filling Order [Ar] 4s1 3d5 [Ar] represents the closed-shell electron conf...
By diagonalizing the complete energy matrix of a d4 configuration ion in tetragonal symmetry, the zero-field-splitting parameters a, D and F of InP:Cr2+ have been studied. The local structure distortion parameters ΔR = 0.08 and Δθ = 1.01 were estimated. They show an expansion distortion ...
To optimize AC adsorption performance to improve their electronic conductivity, and provide extra ion storage sites and constraint capacitance, nitrogen (N) doping is an essential effective approach. With the addition of N into the structures of carbon-based composite, the doped N2atoms cause local ...
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 ...
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...
