In the first few superactinides, the binding energies of the added electrons are predicted to be small enough that they can lose all theirvalence electrons; for example, unbihexium (element 126) could easily form a +8 oxidation state, and even higher oxidation states for the next few eleme...
Electrons ejected from the 2a1, 1e and 1a1 orbitals of NH3 have been detected in coincidence with forward scattered projectile electrons of 3.5 keV over a range of energy losses from 13–50 eV. The coincidence intensities for each of the three orbitals were transformed into relative values of...
1.Whattype of elements give off valence electrons to achieve a configuration of a noble gas? Metals give off valence electrons. Metals form cations 2.How is a covalent bond formed? Covalent bonds are formed when electrons are shared to complete an octet. 3.Write the Lewis structure for NH3...
The4felectrons of lanthanides, because of their strong localization in the region around the nucleus, are traditionally included in a pseudopotential core. This approximation is scrutinized by optimizing the structures and calculating the interaction energies ofGd3+(H2O)andGd3+(NH3)microsolvation complexes...
Since Wilmshurst's method for calculation of group electronegativity has some defects, the revised method was proposed for counting the number of valence electrons (n*) on the central atom A in radical AB, and group electronegativities o... N Inamoto,S Masuda - 《Chemistry Letters》 被引量...

Ground and Excited State Properties and Vibronic Coupling Analysis of the Creutz−Taube Ion, [(NH3)5Ru-pyrazine-Ru(NH3)5]5+, Using DFT In this work we demonstrate that DFT does offer a unique tool for handling the localization−delocalization of electrons in mixed-valence systems and ......
A study of the charge distribution calculated for covalent bonds shows that the early picture of a bond as being associated with a build-up of charge between the nuclei is still valid. However, if bonding electrons are drawn into this region, other electrons tend to get forced out of it; ...
