The chemistry of bridging methylene metal dimers and the value of the /sup 13/C NMR chemical shifts have been interpreted as due to a partial negative charge on the carbon atom. PES yields a C/sub 1s/ binding energy indicative of -0.5 e charge. However, for (..mu..-CH/sub 2/)(MnC...
A novel type of metastable complexes of metal (such as Na) atoms with a super-fluorinated carbon molecule is investigated, with a carbon atom exhibiting a unique, pentavalent character. It is induced by the charge transfer from the alkali metal component, followed by a geometric compression of ...
The Lennard–Jones model of the carbon atom47 is taken for the electrode, and a coarse-grained model (Fig. 1b), which provides accurate thermodynamic and dynamic properties, is adopted for the ionic liquid, [EMIM][BF4] (ref. 48). All simulations are performed in the NVT ensemble using ...
numbers from unity upward and divided into sevengroupshaving properties closely related to the first seven of the elements then known:hydrogen, lithium,beryllium,boron,carbon, nitrogen, and oxygen. This relationship was termed thelaw of octaves, byanalogywith the seven intervals of the musical scale...

Electrons exist in energy levels or shells around the nucleus, and each shell can hold a specific number of electrons. Example of an atom: Atomic Number: 6 (Carbon) Protons: 6 Neutrons: 6 Electrons: 6 (2 in the first shell, 4 in the second shell) 反馈 收藏 有用 解析 免费查看答案及...
The effect of molecular structure upon the response of the flame ionization detector It is known that the response of the FID is proportional to the number of carbon atoms in hydrocarbon molecules. If there is a heteroatom in the molecule, ... M Kállai,J Balla - 《Chromatographia》 被引量...
ab initio density functional theory (dft) calculations are performed to study the diffusion of atomic hydrogen on a mg(0001) surface and their migration into the subsurface layers. a carbon atom located initially on a mg(0001) surface ca... AJ Du,SC Smith,XD Yao,... - 《Journal of Phys...
In this study, we have theoretically examined the thermodynamic driving forces for the charge-induced nucleation, in general, and have applied this idea to the nucleation of the charged carbon-atom cluster. It was shown that the short-range ion-induced dipole interaction and the ion-solvation ...
