Cu = [Ar]3d104s1this configuration does not follow the n+l rule. in other words if you use box notation to map out the electron configuration of Cu2+you dont fill the 4s orbital first. so,if:Cu=[Ar]3d104s1=29=atomic number=nu-mber of electrons ...
The observed g -values are consistent with a d 9 -configuration ion at a tetragonally distorted octahedral site from which it is inferred that Cu 2+ substitutes at the Ti-site.doi:10.1088/0953-8984/7/31/015D.J. KeebleZ. LiM. Harmatz...
The spectra are analyzed by configuration-interaction calculation on the FeS4 cluster model; the analysis yields the S 3p→Fe 3d charge-transfer energy Δ close to zero, indicating strong covalency between the Fe 3d and S 3p orbitals. This situation is reflected upon the reduced Fe magnetic mom...
The effective construction of electron transport channels has essential significance for electron-transfer rate enhancement in REDOX processes during peroxymonosulfate (PMS) activation. This study focuses on the establishment of Cu-involved covalent bonds due to the unique electron configuration of Cu ions...
The method of electron configuration analysis for many-system interactions (ECAMSI) has been developed and applied to the π electronic structures of polycyclic molecules. The HMO-ECAMSI calculations have been carried out on acenaphthylene, pleiadiene, pyracylene, acepleiadylene, and dipleiadiene. ...

• 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 ...
Differential cross sections for the elastic scattering of electrons from the ground states of copper for the configuration 3d 10 4s and the excitation state 2 D with the configuration 3d 9 4s 2 have been calculated. Local density approximations to the exchange and correlation potentials have been ...
4A). Later studies identified a number of problems associated with the conventional configuration, such as high internal resistance, low voltage production, pH imbalance and microbial inhibition due to migrated ions, membrane fouling and scaling, and migration of non-selective ions (Cao et al., ...
