鹵原子在它們的介電子層含有七個電子。 -
Halogen atoms contain seven electrons in their valence shell, and, consequently, are monovalent.
鹵原子在它們的價電子層含有七個電子，因此是一價的。 -

一般認為，在金屬中價電子容易脫離個別原子。 -
One way to simplify the problem is to divide the electrons into two groups: the 36 core electrons, and the two 4s valence electrons.
簡化此問題的一個方法是把電子分成兩組：36個原子實電子和2個4s價電子。 -
In the band structure, one band that is completely filled with electrons is termed valence band
在能帶結構中，完全填滿電子的帶被稱為價帶。 -
A set of eight valence electrons in an atom or ion, forming a stable configuration
八重態在一個原子或離子中，形成穩定組態的一組八個化合價電子 -
The highest - energy band containing electrons is called the valence band, and the next higher one is the conduction band
填有電子而能量最高的能帶稱為價帶，相鄰的更高能帶稱為導帶。 -
As such, the representation of the deep overlapping of the wavepackets of valence electrons as well as of other nuclear events is beyond any credible hope of quantitative treatment via quantum mechanics or chemistry on conceptual, mathematical and physical grounds
這樣，對原子價電子深深重疊的波包，以及其它核事件的描述，在概念、數學和物理基礎上均超越了通過量子力學或化學進行量子處理的任何可靠的希望。 -
The reason is that their valence band is full of electrons, which obstructs current flow
因為它們的價帶填滿了電子，使電流無法流動。 -
We also have analyzed the photoluminescence ( pl ) spectra of some zno films, it turns out that the emission of ultraviolet light comes from the radiative recombination of excitons within nano - crystal energy band - gap, and the pl peaks move to smaller wavelength because zn are substituted by fe, co, and cu, which cause the size of the film grains smaller and the effective band - gap bigger. the red emission of zno films is due to, on the one hand, decrease of the film grains size which causes the emission intensity smaller and smaller until it disappears abruptly, on the other hand, the transition of electrons from deep donor level of the oxygen vacancies to the valence band
另外，我們還對薄膜光致發光性質進行了分析和研究，結果表明：納米結構zno薄膜的紫外發光來源於帶間激子的輻射復合發光， pl譜的帶邊發射峰發生藍移是由於fe 、 co 、 cu對zn的替代使薄膜粒子的尺寸減小，使薄膜的有效帶隙增寬； zno薄膜的紅色發光，一方面是zno顆粒尺寸的減少，帶間的激子發射峰越來越弱直至猝滅，另一方面主要是與zno晶格中的o空位有關，由深能級復合發光引起紅光發射。 -
The origin of the above shortcomings is in the structure of molecules themselves, where we have valence electrons which can interact at mutual distances of the order of the size of their wavepackets, which is a distance 108 times smaller than the atomic distances
導致上述短處的根源來自其分子結構本身我們有能夠在其波包尺寸相互距離相互作用的原子價電子，該距離為原子之間的距離的1 108 。
