The electronic structures of the chalcopyrite-type CuFeS2 and CuAl0.9Fe0.1S2 are studied by x-ray photoemission (XPS), resonance photoemission, Auger-electron, optical reflectance, and electron-energy-loss (EELS) spectroscopies. The Fe 3d-derived states are revealed by the valence-band XPS spectr...
As a result, it shows an unexpectedly higher turnover frequency (435h) than that of Cu-N(190h), Cu-N(90h) and Cu nanoparticle (58h) catalysts, respectively. This work provides a facile and efficient method for regulating the electron configuration of single-atom catalyst and generates a ...

• Hund's rule: The lowest energy e - configuration (called the ground state configuration), is the one with e - unpaired as long as possible and the electron spin maximized • Exceptions: Common ones: Cr, Mo and Cu, Ag, Au because half-filled and filled subshells are more stable ...
Write the full electron configuration for the {eq}Cu^+ {/eq} ion. Electron Configuration: The electron configuration of an atom or ion is the arrangement of the electrons in the respective orbitals. Depending on the orbital, the number of electrons that it can hold also varies. As an examp...
An element with the electron configuration 1s^22s^22p^63s^23p^6 has how many electrons? What is the correct electron configuration for Se? What is the electron configuration of Cu^2+? Use the inner electron configuration format. Which of elements 1-36 have one unpaired electron in the ground...
This work indicates that Cu ++ forms either a chelate binding one of the DO prosthetic groups (pyridoxal phosphate or flavin adenine dinucleotide) to the apoenzyme, or else a chelate which holds the DO in a configuration in which it is an active enzyme. Changing or breaking this chelate in...
With this work, we begin our treatment of the transition metal electron affinities. A procedure, REDUCE, for reducing the number of parental couplings per configuration present in the first order wave function from as many as 100 to only a few is introduced. Progress toward a comprehensive ...
the electron with the highest value for n (i.e the number of the shell) and then the highest l value (s, p, d, f).So I would say rleung is right to believe the electron configuration of the Co2+ ion is [Ar]3d7 because the two 4s electrons are lost first. I can't imagine ...
