The design of planar tetracoordinate carbon (ptC) has always been a challenge due to its unique bonding mode that necessitates the perfect balancing between the carbon center and surrounded ligands both electronically and mechanically. A unique class of 18-valence-electron (18ve) template, i.e....
The valence electron structure (VES) of RuB2 and OsB2 were calculated by the empirical electron theory (EET) of solids and molecules and compared with the results derived from the first-principles calculations. The distributions of covalent electrons in different bonds indicate that B-B and B-Me...
The valence electron structure of Fe_2B phase was studied on the basis of Yu's empirical electron theory of solids and molecules.The values of valence electrons on every bond in an atomic coordinate cluster were calculated by the method of bond length difference(BLD). The results showed that ...
On the basis of these measurements electron transfer occurs within the porphyrin ring and the metal-porphyrin bonding consists of covalent-sigma-bonds between d(n)sp valence electrons of neutral metal and pyrrole p electrons of the porphyrin. The (Cl8TPP)Fe(III)(ClO4) and (Cl8TPP)Mn(III)...

For a metal such as zinc, which donates two electrons to achieve a stable electron configuration, the oxidation number is +2. Nonmetals, which commonly accept electrons and in compounds exist in the negative, or anionic, state, are assigned negative oxidation numbers (see anion). The oxidation...
This is determined based on the number of electrons that would be added, lost, or shared if it reacts with other atoms. Valence is denoted using a positive or negative integer used to represent this binding capacity. For example, common valences of copper are 1 and 2. Table of ...
