Assertion:Cu2+is more stable thanCu+ Reason: Electrode potential is more important in determining stable oxidation state than electronic configuration. View Solution Free Ncert Solutions English Medium NCERT So
A broader visible emission band was obtained for all the samples centered at 428 nm, and is attributed to the recombination of electrons deeply trapped in oxygen vacancies with photogenerated holes [39]. As we increase the doping concentration of Mg into ZnFe2O4, overall intensities of the ...
We know that the elements having similar valence electronic configuration belong to the same group of the periodic table. Therefore, elements A and B having three electrons in the valence shell belong to the same group i.e., group 13 of the periodic tabl
the abundance of boron has been pointed out as a possible reason for MgB2’s superconductivity, considering both covalent B-B and ionic B-Mg bonding. It is important to note that these
The increase in the work function after the adsorption of Cl atoms is due to the transfer of electrons from the higher Mg electron orbital to the lower Cl electron orbital. As a result, the Cl adsorbing atom has a negative charge and the Mg (0001) surface has a positive charge, thus ...
The Cr3+ cation possesses three electrons in its outer shell (d3 system). The energy matrices and energy level diagram developed by Tanabe–Sugano were used to understand the photoluminescent properties observed herein [40–43]. Analyzing the d 3 energy level diagram for octahedral ...
A critical improvement in the quantum dot LED (QLED) technology was achieved when zinc oxide nanoparticles (NPs) were first introduced as an electron transport layer (ETL) material, which tremendously enhanced the device brightness and current efficiency due to the high mobility of electrons in ZnO...
(#191) containing alternating layers of Mg and B atoms stacked along the\(\overrightarrow{c}\)lattice direction, as shown in Fig.1(a)42. The bonding between the Mg and B atoms is purely ionic, which means that Mg atoms donate two electrons to B atoms, thereby making each Mg 2+and...

The truncation criteria of the two-electrons integrals (Coulomb and HF exchange series) was set as 8, 8, 8, 8, and 16, and the energy convergence threshold with 10−9 Hartree for the SCF iterations was chosen for the sake of high accuracy. The convergence thresholds of the root-mean-...
