One way to simplify the problem is to divide the electrons into two groups : the 36 core electrons , and the two 4s valence electrons 简化此问题的一个方法是把电子分成两组: 36个原子实电子和2个4s价电子。
The atom of which number of valence electron is half of the sub - layer of electron has magnetic entropy value according to the theoretic calculation 根据理论计算,价电子为半满的原子全角动量量子数j值比较大,从而有大的磁熵值。
The valence electron structures of maid phases and phase interphase boundaries in al - li - cu based alloy were analyzed according to the empirical electronic theory in solid and molecules ( eet ) 本文运用固体与分子经验电子理论(简称eet理论) ,对al - li - cu系合金相空间和相界面的价电子结构进行计算。
The ability of carbon to form stable compounds in such astonnishing numbers arises in that it utilizes its four valence electrons completely in the establishment of four covalence , its valence shell becomes saturzted 试译一下:碳能组成(有着)如此惊人数量的稳定的化合物在于它在四价共价健的建立中充分利用自己的四价电子,它的化学价层才能得以饱和。
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 导致上述短处的根源来自其分子结构本身我们有能够在其波包尺寸相互距离相互作用的原子价电子,该距离为原子之间的距离的1 108 。
