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...
Re: electron configuration « Reply #4 on: May 19, 2006, 08:27:53 PM » I hate to be the guy that always disagrees with people () but I am sure that when cations are formed, they lose their outer most electron i.e. the electron with the highest value for n (i.e the numb...
In this work, regulable Cu–O–C configuration was constructed through tunable ratio of copper aluminum oxide (CuAlxOy) and porous g-C3N4 (p-CN), employed as electron transfer bridge for Cu(II)/Cu(I) redox behavior modulation to realize sufficient peroxymonosulfate (PMS) activation. A series...
You will also need to be able to select the noble gas that completes a configuration for a given element. [ ? ] 5s2 4d10 4p1 [Kr] 5s2 4d10 4p1 Indium The noble gas is always from the end of the previous row, so you just go up and over. This represents that everything before...
• 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 ...
Only other exceptions in the transition elements are Cu (29), Mo (42), Ag (47) and Au (79). (Others will not be studied.) (d) 4s2 4p6 5s2 (e) 5s2 5p5 • • • • Expected configuration: [Ar] 4s2 3d4 Actual configuration [Ar] 4s1 3d5 • CHEM. 2AP UNIT 5 ...
