Electron的强大功能得益于它的arrangement around the nuclei of atoms, 接下来我们从三个层次介绍电子的排列方式。 首先来学习一个名词: QUANTUM SHELLS:electrons can only exist in certain well-defined energy levels. 以K原子为例,从里到外分别是the fi...
Energy Levels of an Atom An atom's electrons do not all exist at the same energy level. While the Bohr model is a great place to start understanding the different energy levels and how they affect electron positioning, it does not accurately describe electron behavior. Atomic orbital theory,...
In atoms, the electron energy levels are quantized and discrete and the energy gap between the highest occupied and lowest unoccupied orbital (HOMO–LUMO) determines to a large degree their stability, reactivity, and electronic properties. As atoms aggregate to form clusters or molecules, these ener...
In the investigation of the optical and magnetic properties of the semiconductors containing transition-metal ions, the one-electron orbital cannot be treated with a pure d orbital because of a strong covalence. This paper presents the energy matrix of the d*(8) and d*(2) (d* means a ...
The valence electron distribution of a free independent transition atom (e.g., Co) is spherical, and its five d-orbital energy levels are degenerate. In the case of transition-metal oxides, splitting of the d-orbital energy levels occurs under the crystal field of polyhedra, and the redistrib...

indicate that the new electronegativity scale X N is in conformity very much with the Pauling scale which is widely accepted.Moreover,electronegativities of hybridrized orbitals sp,sp 2,sp 3 for carbon atom can be also obtained from the connectivity index of valence orbital energy levels. ...
I could get my invested energy back by dropping the electron from infinity to its now empty orbital. This amount of energy released by the dropping electron is the electron affinity. If, somehow, I would cause the electron to be attracted by the nucleus only half as strongly, then the ...
7.On the Influence of Orbital Energy of Halogenous Atoms on Certain Properties of Halogens;卤原子的价层轨道能量对卤素某些性质的影响 8.a theory of atomic structure that assumes an electron orbiting a nucleus can only be at certain energy levels.假设电子需要有一定能量才能环绕核子轨道的原子结构理...
electron orbital. Higher values ofnmean more energy for the electron and the corresponding radius of the electron cloud or orbital is further away from the nucleus. Values ofnstart at 1 and go up by integer amounts. The higher the value of n, the closer the corresponding energy levels are ...
